FPGA Implementation of D8PSK Demodulator

Differential phase shift keying (DPSK) is a modulation scheme that facilitates non coherent demodulation and is employed for various applications such as Wireless Local Area Networks (WLANs), Bluetooth and RFID communication. In this paper, design, development and hardware implementation of a new demapping scheme for Differential 8-PSK (D8PSK) demodulator on a Zynq 7000 FPGA based ZED board is proposed using the concepts of model based design. The proposed work can be easily extended to other M-ary DPSK schemes.
