Improving HiperLAN/2 Physical Layer Model Based Multiwavelet Signals by using Block Turbo Codes System

Abstract

The progress of broadband wireless communication systems should cope with different performance restrictive challenges that include channel fading as well as size and power limitations at the mobile units.  In this paper, the Block Turbo Codes (BTC) is evaluated for the HiperLAN/2 OFDM system based multiwavelet signals. Matlab software-simulated physical layer performance results are presented show that Packet-Error- Rate (PER) performance is improved when using block turbo codes in the HiperLAN/2 system. We also show that the frequency interleaver has a big impact on the performance of the turbo decoding process and that increasing its size lead to good performance when compared to the convolutional code
