Tīmeklis2024. gada 18. maijs · Four blue spots show QPSK constellation diagram, and red spots show constellation diagram of a QPSK signal with AWGN added. $\endgroup$ – Emir May 18, 2024 at 11:44 The most straightforward type of PSK is called binary phase shift keying (BPSK), where “binary” refers to the use of two phase offsets (one for logic high, one for logic low). We can intuitively recognize that the system will be more robust if there is greater separation between these two phases—of course it … Skatīt vairāk BPSK transfers one bit per symbol, which is what we’re accustomed to so far.
