20120244817 | Apparatus and Methods For Estimation of a Subchannel Power Imbalance Ratio (SCPIR) - Described herein are various methods for a communication device (e.g., a mobile station) receiving an AQPSK modulated signal (e.g., a VAMOS signal) to estimate a subchannel power imbalance ratio (SCPIR). Advantageously, the methods are not computationally complex and do not suffer from poor numerical performance. | 09-27-2012 |
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. | 03-21-2013 |
