Abstract
A method of allocating optimum orthogonal function codes to a reverse link in a communication system which has one base station and a plurality of mobile stations, comprising the first step of detecting characteristics of reverse channels from a desired one of the mobile stations to the base station, the second step of obtaining an orthogonal function code based on the detected characteristics of the reverse channels, and the third step of allocating the obtained orthogonal function code to the desired mobile station. According to the present invention, optimum Walsh codes are allocated for distinction between mobile station signals of the reverse link to minimize an interference between mobile stations in a CDMA communication system. Therefore, an inter-mobile station interference through a multipath can be minimized to significantly enhance a signal-to-noise ratio of the reverse link.
