PARTIAL PARALLEL INTERFERENCE CANCELLATION METHOD AND RECEIVER WITH ARQ FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a partial parallel interference cancellation method and receiver with an ARQ function.;SOLUTION: This method includes acquisition of synchronizing information of all users from received signals, acquisition of parameters of user channels, respectively acquiring initial detection results of the users, acquisition of packets corresponding to user information detection results depending on each initial detection result, discrimination of K-sets of packets respectively, detection of first transmission packets of the users in multistage to acquire symbol sequence detection results of the users, or acquisition of symbol sequence detection results in present packet repeat processes of the users by providing storage detection results of users' first or repeat packets to received repeat packets so as to detect uses' repeat packets in multistage when the received packets are the repeat packets, discrimination of whether or not the packets are accurately received to provide ACK or NACK corresponding to the discrimination results to information decoding results in decoding results, and output of the results of the provision as final detection results of the users.;COPYRIGHT: (C)2007,JPO&INPIT
