Combined Coding And Modulation Employing Multi Phase Shift Keying Modulation, Huffman Codes And Array Codes
In this paper a technique for combining Huffman code, array code and phase modulation is proposed with a view to reduce redundancy, provide error control and simultaneously optimise on channel bandwidth. The combined scheme provides a reduction in overall complexity of the communication system as compared to a separate system. The Block Coded Modulation (BCM) scheme is suitable for both data transmission and information storage. The trellis design algorithm of the scheme is proposed and error performances for the same employing MPSK modulation are compared with those using Huffman followed by array codes and modulation.
