WebSep 30, 2024 · BPSK也是这个道理。虽然每个 T_{\\rm b } 内它是一个单一频率的正弦载波,但不同比特之间的信号变化有丰富的频率分量,导致BPSK的频谱不同于单频正弦波 … WebApr 8, 2010 · BPSK stands for Binary Phase Shift Keying. It is a type of modulation used in digital communication systems to transmit binary data over a communication channel. In BPSK, the carrier signal is modulated by changing its phase by 180 degrees for each binary symbol. Specifically, a binary 0 is represented by a phase shift of 180 degrees, while a ...
