摘要: Convergence analysis of iterative detectors for narrow-band multiple access is performed using extrinsic information transfer charts. The system has no bandwidth expansion, so K users use the same as a single user. load (the number bits used per channel) therefore higher than in, example, conventional CDMA systems. provides useful guidelines on how to combine outer codes with chosen mapper different loads system. Both memoryless mappers and differential are evaluated. We present limitations measured maximum required SNR scenarios.
