摘要:
A receiver is described. The receiver includes a filter configured to receive a quadrature phase shift keying (“QPSK”) signal. Further, the receiver includes an amplifier coupled with the filter. And, a QPSK decomposition filter is coupled with the amplifier. The QPSK decomposition filter is configured to generate a first BPSK signal based on the QPSK signal and a second BPSK signal based on the QPSK signal.
