Title: Masoud Salehi: Innovator in Underwater Acoustic Telemetry

Introduction

Masoud Salehi is a notable inventor based in Westwood, MA (US). He has made significant contributions to the field of underwater acoustic telemetry, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is the "Iterative Decision Feedback Adaptive Equalizer." This invention provides a receiver for underwater acoustic telemetry that combines a decision feedback adaptive equalizer structure with a modified turbo-equalizer structure. The modified turbo-equalizer is designed with significantly reduced complexity, allowing the decision feedback adaptive equalizer to process multiple data channels and produce a single symbol data output stream. This output is then applied to the modified turbo-equalizer, which can utilize either a hard Viterbi decoder for single iteration processing or a soft in/soft out decoder, such as a MAP decoder, for multiple iterations. The iterative process enhances performance compared to a standard decision feedback equalizer while maintaining lower complexity than traditional turbo-equalizers.

Another significant patent is the "Two Stage S-Random Interleaver." This invention provides a method, computer medium, and device for a two-stage S-Random interleaver constructed based on two optimization criteria. The design maximizes the distance spectrum properties of the code by increasing the minimum effective free distance. Additionally, it reduces the correlation properties of the extrinsic information fed into the next stage decoder. This innovative approach results in a more efficient S-random interleaver with increased iterations, thereby maximizing the bit error rate (BER) performance of the code concerning iterative decoding.
