Abstract

A CMOS VLSI pseudo-noise code generator for battery-powered spread spectrum communication systems exhibits a 50% smaller delay-power product than an equivalent binary number system implementation. The design employs small LFSRs modulo single prime powers operating in parallel to generate uniformly distributed variates modulo the product of the primes. The design employs the one hot residue (OHR) number system, which is shown to be attractive for high speed, hardware efficient applications. An example FH SS/MA application of the generator is given using an OHR frequency synthesizer
