Abstract
An uplink multiple access method based on the user-specific frozen bit patterns of polar codes assigned to users and relevant transmitter-receiver embodiments. The method includes encoding the information bits with a polar encoder by using the binary-valued, user-specific frozen bit patterns in frozen bit locations during encoding operation. The method further includes mapping of coded bits with symbols to be transmitted and baseband-to-RF processing performed on the symbol sequence. The generated signals of each user are transmitted by using the same time-frequency resources. The method further includes to receive the superposed signal of multiple users transmitted by means of relevant uplink radio channels. The method further includes an RF-to-baseband conversion on the received signal and detecting and decoding each user data by using an interference cancellation multiuser detector and a polar decoder that uses binary-valued pattern sequences assigned to the users in the frozen bit locations.
