Efficient FPGA Implementation of Chaotic based Communication System with Polar Encoding

Abstract

Polar code has become the coding scheme of the control channel in the 5th Generation (5G) wireless systems. Reduced complexity is the most attractive feature in encoding and decoding schemes. One of the main characteristics of 5G networks is the enhanced mobile broadband (eMBB) communications. The characteristic of chaotic signal such as wideband spectrum, good randomness behavior, easy to generate and perfect correlation properties making it suitable for 5G communication system. The implementation of polar coding with chaotic modulation plays a vital role in communication systems for 5G environments. Parallel processing capability with Field Programmable Gate Array (FPGA) reduce the complexity and perform the encoding and decoding processing faster. In this paper, an efficient communication system consists of polar codec and Chaotic Shift Keying (CSK) modulator has been designed in Xilinx System Generator (XSG). The designed system is implemented successfully in FPGA hardware using Nex4DDR-Artix7 and Genesys2-Kintex7. The hardware results proved that the required resources are reduced as compared with literature. The number of DSP blocks is 120 while the time delay is 14.479 ns.
