Abstract :
Intersymbol interference in direct detection optical systems can limit the channel spacing in frequency division multiplexing systems, and limit data rates and transmission distances in long distance transmission systems. We present minimum mean-square-error electrical filters to compensate for optical intersymbol interference. The performance of these filters is compared with a matched filter and the performance of an electrical filter with a rectangular response, for M-ary amplitude modulation
