Abstract: signal Multi-divisional access is used as a 3GPP uplink transmission scheme. In this document, we propose a new Multi-Channel Multichannel Detection (CES) detector. In multi-user MIMO systems. Compared to the conventional SIC receiver, this system overcomes the problem of error propagation in the interference removal process by combining fine resolution output and channel decoding. The effect of future channel estimation error is achieved through the use of our Messy technology, the best results are obtained using our proposed technique.
