Wimax (IEEE 802.16 m) system based on space time block code and discrete multiwavelet transform and implementation in FPGA

Abstract

MIMO (Multiple Input Multiple Output) scheme uses transmit diversity technique which results in high throughput with increased channel capacity. The complexity of MIMO system increases the area and power requirements of the system. The proposed work is to achieve good spectral efficiency and reduction of interference by introducing multiwavelet with MIMO technology. The improvements directly results in reduction of BER (Bit Error Rate) for a given SNR (Signal to Noise Ratio). Implementation of the proposed scheme in FPGA (Field Programmable Gate Array)—virtex5 (xcvlx30t-1f665) shows a considerable improvement in speed and area when compared with the existing methods.
