Abstract
A method is based on the user-specific frozen bit patterns of polar codes assigned to users. At the transmitter, the binary-valued user-specific frozen bit pattern sequences to be used in frozen bit locations are determined for each user, the information bits of each user are encoded using a polar encoder, and the binary-valued user-specific frozen bit patterns are used in frozen bit locations during encoding operation to improve the performance of the downlink multi-user MIMO system. Coded bits are mapped to symbols to be transmitted, and the symbols are mapped to the MIMO layers. Then, multi-antenna precoding is applied and baseband-to-RF processing is performed onto the precoded symbols to transmit the signal. The signal of all users is transmitted at the same time-frequency resources using transmit antennas. Each receiver receives the transmitted signal which is transmitted through respective downlink channels. Each user performs RF-to-baseband processing to their respective received signal.
