Implementation and Estimation of Wireless Communication Channel

Haider TH. Salim ALRikabi

Abstract: In a wireless network, users can relay on information that exploits cooperative diversity, thereby ?increasing reliability. The new generation wireless systems (3G/4G) are designed for this purpose. ?The notable characteristics of 3G/4G, is that it provides high data rate transmission at a data rate ?up to 348 kbps/2 Mbps for 3G and 100 Mbps/1 Gbps for 4G. Designing the system for such high ?data rate transmission has become very challenging for wireless systems where the multipath ?fading is an important factor. Due to the increased demand in the recent years, researchers are ?ongoing in the industry and academic to increase the capacity performance of wireless systems ?through antenna diversity. To mitigate the small scale fading effects, a diversity mechanism have ?been introduced in this work. The collected results have been done by using Matlab 2015 ?Program.?
