Iterative equalization enhanced high data rate in wireless communication networks

Abstract

There has been a demand for high data rate for wireless communication system devices, mainly mobile multimedia applications. This paper investigates the suitability of Turbo Equalization as a means of achieving low bit error rate in the future high data communication systems. Turbo equalization is an approach to coded data transmission over channels with Inter-symbol interference (ISI) which can yield additional improvement in bit error rate. The paper demonstrates that at higher modulation scheme using iterative equalization method, high date rate can be achieved. The performance evaluation shows that turbo equalization is beneficial for higher modulation and thereby increase data rate with a reasonable complexity.
