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

摘要

We illustrate the low-power advantages of the One-Hot ResiduenNumber System by presenting a pseudonoise (PN) code generator fornbattery-powered spread-spectrum communication systems. It exhibits ansignificantly reduced delay-power product below an equivalent binarynnumber system implementation. This advantage is obtained because thennumber system allows the decomposition into small serially enabled unitsnof the large linear-feedback shift register required to generate the PNncode. Additionally, it allows fast and efficient computation of sums andnproducts. An example frequency-hopped spread-spectrum application of thengenerator is briefly presented using a previously designed frequencynsynthesizer
