The receive adjust module adjusts coordinates of the multiple or plurality of amplified inbound RF signals based on the receive mode. | 2013-12-05 |
20130322566 | PRECODING METHOD, PRECODING DEVICE - Disclosed is a precoding method for generating, from a plurality of baseband signals, a plurality of precoded signals that are transmitted in the same frequency bandwidth at the same time. According to the precoding method, one matrix is selected from among matrices defining a precoding process that is performed on the plurality of baseband signals by hopping between the matrices. A first baseband signal and a second baseband signal relating to a first coded block and a second coded block generated by using a predetermined error correction block coding scheme satisfy a given condition. | 2013-12-05 |
20130322567 | Generation and Application of a Sub-Codebook of an Error Control Coding Codebook - There is provided a method of encoding and decoding data using an error control code having a codebook G. The codebook G is a sub-codebook of a codebook P. Each codeword g in the sub-codebook G has an autocorrelation amplitude that is different from and higher than each correlation amplitude between g and each of the other codewords in the sub-codebook G. In one specific embodiment in which the codebook P is that of a Reed-Muller code, using G instead of P reduces the likelihood of the presence of more than one maximum correlation amplitude when computing the non-coherent decision metric during decoding. | 2013-12-05 |

20130322569 | Digital Mobile Passive Leak Detection for Broadband Communication System - Passive detection of a quadrature amplitude modulated (QAM) signal amid noise is achieved by detection of a spectral component of a detected signal that corresponds to a known QAM symbol rate in, for example, a QAM modulated broadband communication system (BCS). Improved authentication can be provided by simultaneously detecting symbol rate components in two or more QAM bands. No modification of a broadband communication system such as by including a marker signal is required and thus there is no requirement for dedication of a portion of the broadband communication system spectrum or problem of marker signal interference with BCS signals. | 2013-12-05 |
20130322570 | PHASE NOISE EXTRACTION APPARATUS AND TECHNIQUE - A phase noise extraction apparatus and technique that extracts phase noise induced by a component of a transmitter from a radio frequency (RF) signal and attenuates noise induced from other sources. The RF signal is digitized, modulation is removed, and the carrier is suppressed to provide a noise signal including the phase noise and the noise induced from the other sources. A complementary autocorrelation operation is applied to the noise signal to attenuate the noise from the other sources. The correlated signal is transformed into the frequency domain to generate a power spectrum of the phase noise that may be measured or displayed. | 2013-12-05 |
20130322571 | SAMPLE RATE ESTIMATOR FOR DIGITAL RADIO RECEPTION SYSTEMS - A method and apparatus for adjusting a sample rate for an asynchronous sample rate converter is disclosed. In one embodiment, an apparatus includes an asynchronous sample rate converter (ASRC) that is configured to receive a digital data stream provided at a first sample rate. The ASRC is configured to convert the digital data stream to a second sample rate at which it is output. The apparatus also includes a sample rate estimator coupled to an interface through which samples from the digital data stream are conveyed subsequent to conversion to the second sample rate. The sample rate estimator is further coupled to the ASRC, and configured to adjust the second sample rate based on information obtained from the interface. | 2013-12-05 |
