Interleaver Division Multiple Access（IDMA） is a new multiple access technology. Each user in the system is assigned a different interleaver. Multi-User Detector （MUD） distinguishes users by interleavers. It can be seen as a special kind of Code Division Multiple Access （CDMA） system with low complexity, less number of computations and high spectral efficiency. Orthogonal Frequency Divi- sion Muhiplexing-Interleaver Division Multiple Access （OFDM-IDMA） inherits advantages of IDMA, and reduces Bit Error Rate （BER） in muhipath channel. OFDM-IDMA system based on Linear Con- gruential Intedeavers uses simple Linear Congruential Generator （LCG） to assign interleavers to different users for ensuring the system performance while saving system resource
