PCM
说明: 在实际的调谐解调电路中,采用的是非相干载波解调,本振信号与发射端的载波信号存在频率偏差和相位抖动,因而解调出来的模拟I、Q基带信号是带有载波误差的信号。这样的模拟基带信号即使采用定时准确的时钟进行取样判决,得到的数字信号也不是原来发射端的调制信号,误差的积累将导致抽样判决后的误码率增大,因此数字QPSK解调电路要对载波误差进行补偿,减少非相干载波解调带来的影响。(In the actual tuning and demodulating circuit, non-coherent carrier demodulation is adopted, and the frequency deviation and phase jitter of the local oscillator signal and the carrier signal of the transmitting end are present, and thus the demodulated analog I and Q baseband signals are signals with carrier error.)
