Review of Study and Design of Coding and Interleaving in a MIMO-OFDM Communication System
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
This paper, presents of the review performance analysis of four different channel coding and interleaving schemes for MIMO-OFDM communications systems. A comparison is done based on the BER, hardware implementation resources requirement, and power dissipation. It also presents a memory-efficient and low-latency interleaver implementation technique for the MIMO-OFDM communication system. One aspect of the MIMO-OFDM system that has not been investigated adequately is the effect of using different combinations of the convolutional encoder and interleaver on the system performance. This works focus on a specific FEC mechanism and do not compare their schemes with other alternatives among the four possible schemes. In this paper the performance and computational complexity of the four different convolutional encoding and interleaving schemes are analyzed. The IEEE 802.16 standard is used as a reference for simulation and analysis. This is the method for interleaver design on FPGA and its memory utilization. This project work concentrate on efficient interleaver design for IEEE 802.16 system implemented on FPGA. Our goal is to achieve minimum memory usage, faster interleaving, and increased speed of the overall system. The proposed interleaver, a MIMO-OFDM based transmitter employing a double data stream 2×2 MIMO spatial multiplexing system is built.
