Title:
干渉除去を実行するための受信機および方法
Document Type and Number:
Japanese Patent JP2012532527
Kind Code:
A
Abstract:
To address the need for new interference cancellation techniques that are able to deliver adequate performance but with reduced processing requirements, various embodiments are described. In some embodiments, a receiving device demodulates and decodes (101) at least one first-group user from a multi-user input signal. This multi-user input signal includes at least one first-group user and at least one second-group user, the first-group users having a shorter transmission time interval (TTI) than the second-group users. The receiving device reconstructs (102) an interference signal for each of the first-group users that were successfully decoded and subtracts (103) each interference signal from the multi-user input signal to generate an interference-canceled signal. The receiving device then demodulates and decodes (104) at least one second-group user using this interference-canceled signal.
