Antenna diversity technique improves the instantaneous and average signal to noise ratio (SNR) by combining all the diversity branches. The channel noise and fading reduce the performance of any communication system through making loss of some information of the transmitted symbol. In this paper, we mathematically represented the effect of noise and multi-path fading on the transmitted signal. Then...
Fourth generation mobile systems and services will mainly be characterized by a horizontal communication model, where different access technologies such as cellular, cordless, wireless local area network, short-range connectivity, and wired systems will be combined on a common platform to complement each other optimally for different service requirements and radio environments. To access different...
The next generation broadband wireless communication offers all types of services at very low cost at any time and at any where basis using orthogonal frequency division multiplexing and Worldwide Interoperability for Microwave Access Technology. The transmitted signal is distorted by channel noise and interference from other sources causing bit error. Diversity is a technology to reduce both the...
