- Parallel interference cancellation detector removing interference of multi-user with reference PN code

摘要

The present invention is based on P-a yen (PN) are for using the code to provide a removal parallel interference detection device removing the multi-user interference, this invention PN of each user receives the received signal (Pseudo-Noise) code Filters to mating with a plurality of matched filtered for outputting a signal of the respective user; Receiving the received signal and the reference wake matching unit for outputting the multi-user interference signal by using a reference PN code with a PN code and the orthogonality of each user; In the user signal output from the matching unit and the wake reject the temporary interference to remove the interference by subtracting the multi-user interference signal output from the reference wake matching unit; And a delay unit for delaying the output by the received signal; By cash to regenerate the other user signals undesirable from the received signal input from the delay unit configured to deny a parallel interference claim for determining and outputting the user signal, it is possible to effectively eliminate multi-user interference in a CDMA system, increases the system capacity it is possible to be.
