Performance Analysis of Multimedia Communication System with Enhanced STTD Technique for USN

摘要

In this paper, the new STTD receiver for multimedia communication system in ubiquitous network environment is proposed and the performance of them is analyzed. For the multimedia systems that equip the transmit diversity for forward channel, it is well known that the Tx diversity technique is appropriate for the high rate communications. Adopting the proposed STTD receiver, at 10~(-2) ～ 10~(-4) in bit error rate, the SNR of 0.5dB ～ 2dB performance improvement in AWGN and Rayleigh fading environment has been achieved.
