Reversible logic is the emerging technology in digital era because of its high frequency of operation and small area utilization compared with conventional logic. QPSK (Quadrature Phase Shift Keying) is a type of modulation technique in a wireless communication system, as it supports faster transmission of data compared to other modulation techniques. In this paper, an implementation of QPSK using reversible logic is proposed with some design modifications. Verilog HDL used to implement the proposed QPSK modulators and it will be simulated on the Xilinx ISE 13.2 software platform.
