A Study on the Digital Design for Voice Modem Using the Multicarrier DS-CDMA in Powerline Channels
전력선 채널에서 멀티캐리어 DS-CDMA를 이용한 전력선 음성모뎀의 디지털부 구현에 관한 연구
Abstract
In this paper, we implemented the voice modem using the multicarrier DS-CDMA in powerline channels. Both TMS320C5402 of Texas Instrument and FPGA FLEX 10K EPF10K100ARC240 of ALTERA are used to realize the proposed system. For robustness in the powerline channel, we used multicarrier DS-CDMA modulation, convolutional encoding/Viterbi decoding, and interleaving. Finally, we showed satisfactory performance in the laboratory experiment.
