20090168683 | Method and System for Transmitting Content to a Plurality of Users of a Mobile Communication Network - A scheme substantially similar to that used in HSDPA (in which a downlink channel is provided for data transmission, and at least one associated control channel is provided for transmission of control information including information related to availability of a portion of the transmitted data for the current UE on the downlink channel) is adapted for prolonged high data rate transmission, particularly for MBMS transmission. A duration of the data portions sent on the downlink channel is varied possibly up to high duration values (as compared with a duration of one TTI). User equipment enjoying the service is informed of the duration of the imminent available data portion in a field suitably defined and transmitted as control information on the associated control channel(s). Advantageously, during the “long” decoding of the data portion, the UE does not monitor the associated control channel(s), so that the impact on the terminal's battery is considerably reduced. | 07-02-2009 |

20090135934 | METHOD FOR THE TRANSMISSION ON MULTIPLE-CARRIER COMMUNICATIONS SYSTEMS, AND CORRESPONDING TRANSMITTER AND COMPUTER-PROGRAM PRODUCT - A method for loading bits over a set of subcarriers of a multiple-carrier communications system comprises the operation of associating with the subcarriers respective numbers of bits chosen from among a plurality of available constellations. The method envisages definition of a performance target for the system and execution of bit loading, guaranteeing the aforesaid target on a plurality of subcarriers. The performance target can be a target error rate, such as a bit-error rate (BER), or else be transferred into a constraint, such as, for example, a threshold, in a metric of log-likelihood ratios (LLRs). In this case, there is preferably envisaged application to the signals received within the multiple-carrier system a function that estimates a signal to noise ratio on each sub-carrier. The aforesaid metric of log-likelihood ratios (LLRs) is hence defined as a function of said signal to noise ratios. | 05-28-2009 |
20100166101 | METHOD FOR ESTIMATING THE SIGNAL-TO-NOISE RATIO FOR PACKET TRANSMISSION AND RECEPTION SYSTEMS OF SIGNALS BASED ON M-DPSK MODULATIONS AND APPARATUS THEREOF - A method of estimating a signal-to-noise ratio from a received M-DPSK modulated signal, comprising a sequence of N known symbols, based on a division of the known symbols N and of N samples of the received signal at the output of the channel into a number of blocks B of length L with B greater than one. | 07-01-2010 |
20110135022 | METHOD OF ESTIMATING TRANSMISSION CHANNEL RESPONSE AND DIFFERENCE OF SYNCHRONIZATION OFFSETS INTRODUCED IN A RECEIVED STREAM OF PACKETS OF OFDM DATA AND RELATIVE RECEIVER - An OFDM receiver includes a sampling circuit configured to sample an incoming signal received through a transmission channel and an estimation circuit configured to receive samples of the incoming signal and to estimate transmission channel response and eventual differences of synchronization offsets introduced at a receiver side. An equalizer may be coupled to the estimation circuit and configured to compensate an effect of the transmission channel response and of the differences of synchronization offsets on the received samples and to generate equalized samples. An OFDM detector may be configured to generate a stream of demodulated digital symbols based upon the equalized samples. | 06-09-2011 |

20090297742 | Process for the Production and Form Preservation of an Extruded Product Made of Cementitious material - The present invention relates to a process for the production and form preservation of an end-product made of cementitious material comprising a rapid stiffening phase of the neo-extruded end-product made of cementitious material by irradiation of the neo-extruded end-product with microwaves. | 12-03-2009 |
20100130650 | CEMENT COMPOSITIONS WITH A HIGH PHOTOCATALYTIC POWER AND AN IMPROVED RHEOLOGY - The present invention relates to new photocatalytic cement compositions, especially useful as paints, renders and plasters, provided with a high photocatalytic power and an optimal rheology, evaluated both in the step of preparing and in the step of applying. The compositions according to the invention specifically consist of a combination of organic additives, which, mixed with water and other components, provides cement compositions significantly more effective than the known compositions, both as far as rheology and photocatalytic power are concerned. The cement composition thus obtained associate features which have hardly been compatible up to now: on one side, a good workability (therefore a low viscosity) upon preparation from dry mixtures; on the other side, a good consistency in a wet state just after application. This avoids the occurrence of undesirable dripping before consolidation of the product. Finally, the photocatalytic power results surprisingly higher with respect to that of the known reference compositions when the same photocatalyst is used. | 05-27-2010 |
20110041734 | PAVING WITH A POLLUTION-ABATING ACTIVITY AND A PHOTOCATALYTIC MIXTURE FOR ITS PREPARATION - A new photocatalytic composition is described that is designed for percolation in road surfaces. The composition contains no aggregates, but consists of cement, a photocatalyst, a superfluidifier, a viscosity modifier and an antifoaming agent, in suitable proportions. The composition is applied to porous open-graded asphalt courses, completely filling the cavities down to a thickness coming between 30 and 50 mm. The treated asphalt acquires a strong, durable photocatalytic activity, even when it is submitted to heavy mechanical loads and adverse weather conditions, as in the case of road surfaces in and out of town, liable to intense traffic. | 02-24-2011 |
