Paper Abstract

The hardware implementation of a high throughput Max Log Map Serial Concatenated Convolutional Code (SCCC) turbo decoder for an optical channel employing 64 Pulse Position Modulation (PPM) is described. The Max Log MAP turbo decoder is in contrast to a corresponding optimal log MAP turbo decoder. The Max log MAP decoder is the preferred turbo decoder for applications requiring high throughput. The performance of both the max log MAP decoder and log MAP decoder are compared to the theoretical performance values. Tradeoffs used in the implementation of the high throughput Max Log Map 64 PPM decoder are discussed.
