간접 실내 적외선 채널에서 Pulse-Position Modulation with Trellis-Coded Modulation을 위한 복호기 설계
Design of decoder for Pulse-Position Modulation with Trellis-Coded Modulation on Non-Directed Indoor Infrared Channel
초록
We examine the performance of high-speed non-directed infrared links using pulse-position modulation (PPM) with trellis-coded modulation (TCM) to mitigate the effects of multipath-induced intersymbol interference(ISI) on such links. Using the measured characteristics of multipath indoor infrared channels, we calculate BER curves and ISI power penalties for maximum-likelihood sequence detection of 8-PPM links using rate-2/3 trellis codes operation at 10 and 30Mb/s. Our results indicate that the suggested decoder of PPM with TCM is a very promising decoder on high-speed non-directed infrared channels.
