摘要： A receiver of a wireless communication device, the receiver including a fast Fourier transform module, a first power measuring module, and a gain control module. The fast Fourier transform module is configured to convert a signal from a time domain to a frequency domain. The signal includes a plurality of reference signals. The reference signals have a predetermined power. The first power measuring module is configured to generate a first power measurement of the signal in the frequency domain based on the plurality of reference signals. The gain control module is configured to adjust a gain of the receiver based on the first power measurement.

摘要： A system including a first receiver module and a first interference canceller module. The first receiver module generates a first set of decoded codewords by decoding codewords in a received signal and determines if any of the first set of decoded codewords fails cyclic redundancy check (CRC). The first interference canceller module generates a second signal based on a first decoded codeword from the first set of decoded codewords when (i) any of the first set of decoded codewords fails CRC and (ii) the first decoded codeword passes CRC. By subtracting the second signal from the first signal, the first interference canceller module (i) cancels interference of a first codeword, which corresponds to the first decoded codeword, on a second set of codewords, which includes the plurality of codewords and excludes the first codeword and (ii) generates a third signal, which includes the second set of codewords.
