Modulation and Information Frame of DS-FFH/MSK Hybrid Spread Spectrum TT&C

Analysis, optimization, and implementation of a hybrid DS/FFH spread-spectrum technique for smart grid communications

In recent years, there has been great interest in using hybrid spread-spectrum (HSS) techniques for commercial applications, particularly in the Smart Grid, in addition to their inherent uses in military communications. This is because HSS can accommodate high data rates with high link integrity, even in the presence of significant multipath effects and interfering signals. A highly useful form...

Outage performance of a hybrid DS/FH spread-spectrum signal in an ISM band

This paper develops an analytical model for characterizing the coexistence interference in the unlicensed industrial, scientific and medical (ISM) bands, based on radio frequency measurement results in the 2.4 GHz ISM band. The modeling approach presented here offers a simple methodology for profiling the interference from devices occupying a common spectrum. Outage performance using the interf...

Partial successive interference cancellation in hybrid DS/FH spread-spectrum multiple-access systems

Partial successive interference cancellation is considered in hybrid DS/FH spread-spectrum multiple-access (SSMA) systems. We first show that the lowest BER attained by employing full interference cancellation in DS/SSMA systems can almost be achieved by employing a partial interference cancellation in hybrid DS/FH systems. The reduction in the number of cancellations translates into an allevia...
