چکیده

In this paper performance analysis of IDMA systems is determined using different coding techniques. In this paper we use a receiver diversity approach which is useful in combating the fading in the IDMA scheme. In the transmitter section a single antenna is used where as in the receiver section two antennas are used. A comparative study has been performed between convolutional coding and zigzag coding with and without receiver diversity. Use of receiver diversity improves the bit error performance of the IDMA scheme. Random interleaver has been used in this paper.
