摘要

我们使用l -脉冲位置调制(L-PPM)来检测高速非定向红外链路的性能。当与强度调制和直接检测一起使用时，由于L-PPM具有较高的峰值-平均功率比，因此具有较高的平均功率效率。我们推导了ISI信道上L-PPM链路的误码率表达式。利用多径室内红外信道的测量特性，我们计算了在10和30 Mb/s下工作的2、4、8和16 ppm链路的误码曲线和ISI功率损失。结果表明，L-PPM是一种非常有前途的高速非定向红外通信调制技术。

Performance evaluation of L-pulse-position modulation on non-directed indoor infrared channels

We examine the performance of high-speed non-directed infrared links using L-pulse-position modulation (L-PPM). When used with intensity modulation and direct detection, L-PPM leads to high average-power efficiency, because of its high peak-to-average power ratio. We derive an expression for the BER of an L-PPM link on an ISI channel. Using the measured characteristics of multipath indoor infrared channels, we calculate BER curves and ISI power penalties for 2-, 4-, 8- and 16-PPM links operating at 10 and 30 Mb/s. Our results indicate that L-PPM is a very promising modulation technique for high-speed non-directed infrared communication.<>
