Abstract
A method of paging assigns a unique digital address to mobile stations with each unique digital address being mapped into an orthogonal signal set which is then transmitted to all mobile stations. Each mobile station then correlates a received orthogonal signal function against an orthogonal function corresponding to its address. More particularly, each orthogonal signal set comprises a binary orthogonal signal set such as a set of Rademacher-Walsh functions. Other well known orthogonal function sets can be employed. For example, an mbit address can be partitioned into g binary sequences and each sequence is then uniquely mapped into one of 2.sup.m/g orthogonal functions.
