Explain the function of ber analyzer
WebQPSK is a modulation scheme that allows one symbol to transfer two bits of data. There are four possible two-bit numbers (00, 01, 10, 11), and consequently we need four phase offsets. Again, we want maximum separation between the phase options, which in this case is 90°. The advantage is higher data rate: if we maintain the same symbol period ...
