Rate matching in multichannel systems using RCPC-codes

Rate-compatible punctured convolutional codes (RCPC-codes) are proposed for rate matching in multichannel multiple access systems. The bit error rate performance of a multicode direct-sequence code-division multiple-access (DS-CDMA) based system using RCPC-codes is used to evaluate the proposed rate matching scheme. Comparison with repetition encoding is also made. The RCPC-codes outperforms the repetition codes and can provide a larger span of available channel coding rates. We show that RCPC-codes provide a flexible coding scheme suitable for future mobile radio communication systems.
