PN code generator with low delay-power product for spread-spectrum communication systems

We illustrate the low-power advantages of the One-Hot Residue Number System by presenting a pseudonoise (PN) code generator for battery-powered spread-spectrum communication systems. It exhibits a significantly reduced delay-power product below an equivalent binary number system implementation. This advantage is obtained because the number system allows the decomposition into small serially enabled units of the large linear-feedback shift register required to generate the PN code. Additionally, it allows fast and efficient computation of sums and products. An example frequency-hopped spread-spectrum application of the generator is briefly presented using a previously designed frequency synthesizer.
