As shown in the figure-1, two bits are mapped to one symbol in QPSK. This will reduce the bandwidth to half in comparison with BPSK modulation. In BPSK, one bit is mapped to one symbol. Before mapping, binary data stream is converted from serial to parallel so that two bits are incident simultaneously to two mixer inputs.
