BPSK transfers one bit per symbol. It either transmits 0 or 1 at a time.
QPSK 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).
\(Bandwidth = \frac{{2{R_b}}}{{{{\log }_2}M}}\)
Calculation:
For BPSK M = 2 bandwidth = 2Rb
For QPSK M = 4 bandwidth = Rb
The bandwidth required for QPSK modulated channel is half of the bandwidth of BPSK.
