MGF based closed form solution for channel capacity over generalized-G fading under EGC diversity combining

摘要

The escalating interest in wireless applications need to the continuous increase channel capacity. So channel capacity has been furthermost challenge for the researchers in the field of wireless communication. Capacity analysis and its improvement have been proposed under various scenarios. However, most of them are based on conventional PDF based techniques, some times which cause to be very complex analysis. Analysis becomes more difficult when diversity combining is used for performance improvement. Keeping the above fact in mind in this paper, we have analyzed the channel capacity by using the equal gain combing (EGC) diversity scheme over Generalized-G fading channels. Moreover, we have used moment generating function (MGF) based approach to overcome complexity. Using the MGF of Generalized G fading distribution, we have derived closed form expression for channel capacity under EGC schemes.
