Method and system for compact multi-user serial interference cancellation with simplified generation of spread code sequence

摘要

The initial setting value of the despread code sequence at the point of head time of each cancel processing unit is generated in advance hardware-wise by the despread code generating device (12) of the preliminary processing stage. The initial setting value attached to the received signal block is transmitted to the interference cancel section. In the interference cancel section, the initial setting value of the attached sequence is read out and set up in the despread code generating device (113). Thereby, the initial value for each receiving signal block is correctly set, even if the code sequence changes each time and the despread code sequence can be generated continuously.
