An Algorithm Mixed Turbo Codes with Rake Received in Fading Channel

In this paper, how to analyses the downlink performance of the cellular system combining with site diversity operation and antenna diversity is introduced first. On the basis of Gaussian approximation of the interference components, the changes of bit error rate (BER) in the given set of channel is expressed in receiving signals. By using the Monte-Carlo numerical method, the local average BER is then calculated through comparing the conditional BER with the given set of channel gains. The outage probability is considered to measure the distribution of the local average BER and the downlink capacity. Computer simulation results are discussed finally.
