Figure 7From: Iterative receivers with channel estimation for multi-user MIMO-OFDM: complexity and performanceComplexity-performance trade-off for the different algorithms, when N = 4 receive antennas, at different E b / N 0 and user loads. The figure show the algorithm combination reaching a BER threshold of 10-3 in the fewest number of complex multiplications. The shape indicates the MUD algorithm, while color indicates channel estimation algorithm.Back to article page
