Approximate message passing (AMP) is applicable to massive MIMO signal detection and achieves a high detection performance with low computational complexity. However, when two conditions required by AMP, i.e., the large system limit and a property that each entry of the channel matrix follows an independent and identically distributed complex Gaussian distribution, are not satisfied, the detection performance is severely degraded. It has been found that the degradation is relaxed by introducing a constant multiplier to the observation rate which is the ratio of the numbers of received to transmitted signals. The optimal value of the multiplier depends on the numbers of transmit and receive antennas, signal-to-noise ratio, and other conditions. Learned AMP (LAMP) , which is based on deep unfolding, can perform signal detection while optimizing the multiplier, and has high detection performance. In this paper, we compare the model parameters used for learning. It is found that modification to residual interference power is needed for proper learning when model parameters based on the strict AMP algorithm are used. |
