Abstract :
A family of “multi-length” frequency-hopping codes is constructed. The new codes have asymptotically optimal cardinality as well as zero autocorrelation sidelobes and cross-correlation functions of no greater than one. The use of the new codes in multi-rate, multimedia systems with frequency-hopping code-division is illustrated
