Coverage and Capacity Enhancement in CDMA systems using Antenna array Over in Ricean Fading Channels

One of the most promising techniques for increasing capacity in CDMA system is through the use of antenna array. There are a lot of different ways to calculate capacity of CDMA system. Some of them are quite simple and has an explicit form. The paper introduces to the capacity and coverage in asynchronous Code Division Multiple Access CDMA 2000 based system. Different channel scenario is applied; for the AWGN we use 1 and 4 element antenna arrays to calculate the capacity against coverage assuming different path losses. While as for Ricean fading environment we use 1,4,9 and 16 antenna elements to drive an expression for the signal to Interference plus Noise ratio (SINR) as a function of the number of users (K), number of antennas (Na) and signal to noise ratio levels (SNR). The analytical results will be verified by means of MATHCAD softwear package. ——————————  ——————————
