20130070827 | METHOD FOR BEAMFORMING TRANSMISSIONS FROM A NETWORK ELEMENT HAVING A PLURALITY OF ANTENNAS, AND THE NETWORK ELEMENT - In one embodiment, the method includes receiving a pilot signal from a terminal at a target antenna of the plurality of antennas of the network element, determining an uplink channel estimate for the target antenna based on the received pilot signal, and obtaining a calibration coefficient associated with the target antenna. The calibration coefficient is based on a channel estimate between the target antenna and a different one of the plurality of antennas. The method further includes beamforming a transmission to the terminal using at least the target antenna based on the determined uplink channel estimate and the obtained calibration coefficient. | 2013-03-21 |
20130070828 | Systems and Methods For Demodulating a Signal - A high-sensitivity receiver may be made by using multiple demodulators to demodulate a given signal. For example, the receiver may use a first demodulator to demodulate an input signal into a first sequence of soft bits and a second demodulator to demodulate the same input signal into a second sequence of soft bits. The two sequences of soft bits may then be compared and combined to create a sequence of hard bits. For example, in some embodiments, a soft bit combiner may combine the two sequences of soft bits into a third sequence of soft bits, which may then be input into a decoder to produce the final decoded hard bits. The secondary demodulator may be less complex, less expensive, demand less power, and/or require fewer computational resources when operating, than the first demodulator. | 2013-03-21 |
