Este artigo apresenta uma técnica aprimorada de cancelamento de interferência paralela (PIC) de vários estágios que usa a técnica de transmissão síncrona de link reverso (RLSTT) para melhorar a estimativa de dados no estágio inicial. Como a subtração de um sinal interferente com base em uma decisão de bit incorreta quadruplica a potência de interferência para esse sinal, a taxa de erro de bit de decisão (BER) relativamente alta pode levar a um cancelamento ruim ou até mesmo a um BER mais alto nos estágios seguintes. O RLSTT é uma abordagem robusta que tem em conta o facto de a decisão provisória nas fases anteriores ser menos fiável do que nas fases seguintes e torna o cancelamento anterior mais fiável. A análise demonstra que um melhor desempenho de transmissão pode ser alcançado usando o RLSTT na fase inicial do PIC.

Abstract: This paper introduces an improved multistage parallel interference cancellation (PIC) technique that uses the reverse-link synchronous transmission technique (RLSTT) to improve the estimation of data at the initial stage. Because the subtraction of an interfering signal based on an incorrect bit decision quadruples the interference power for that signal, the relatively high decision bit error rate (BER) may lead to a poor cancellation or even a higher BER at the following stages. The RLSTT is a robust approach which takes into account the fact the tentative decision at the earlier stages is less reliable than the following stages and makes the earlier cancellation more reliable. The analysis demonstrates that a better transmission performance can be achieved by using the RLSTT at the initial stage of PIC.
