Another Approach for Partial Parallel Interference Cancellation
In this paper, a technique for improving parallel interference cancellation (PIC) receiver with linear estimators is studied in a CDMA system under power control and near-far case. By multiplying the received signal for each user in early stages by a factor superior than unity, the proposed technique significantly reduces the harmful impact of the bias upon BER performance and requires only one...
متن کاملParallel Interference Cancellation for CDMA Systems
This paper presents analysis of a multistage parallel interference canceller receiver for a synchronous multiuser CDMA system. At every stage, new estimates of the multiple access interference are formed from innnitely soft decisions for the users' data. These new estimates are then used to cancel multiple access interference and form new decision statistics for the users' data. We show that in...
متن کاملAdaptive multi-stage parallel interference cancellation receiver for multi-rate DS-CDMA system
In this letter, adaptive multi-stage parallel interference cancellation (PIC) receiver is considered for multi-rate DS-CDMA system. In each stage of the adaptive multi-stage PIC receiver, multiple access interference (MAI) estimates are obtained by the sub-bit estimates from the previous stage and the adaptive weights for the sub-bit estimates. The adaptive weights are obtained by minimizing th...
متن کاملComments on "Partial parallel interference cancellation for CDMA"
In this letter we comment on partial parallel interference cancellation as discussed in the above paper by Divsalar et al. The aforementioned work showed that by multiplying symbol estimates by a factor less than unity in early stages of cancellation, the performance of parallel cancellation can be improved relative to full (“brute force”) cancellation. In this letter we analyze the improvement...
متن کاملSoft Decision Parallel Interference Cancellation for Multi-Carrier DS-CDMA
In this chapter, we propose a new scheme for Multi User Detection (MUD) using Parallel Interference Cancellation (PIC) technique. This technique provides a good complexity, latency, and performance compromise. Among spread-spectrum techniques, the most popular one is the Direct-Sequence Code-Division Multiple-Access (DS-CDMA), where each active user’s data is modulated (multiplied) by a unique ...
