Abstract
A method and apparatus for simulating signal interference in one communication channel within a communication system, such as cellular or wireless subscriber telephone and/or data systems. The communication system may be of a cellular type in which users from a plurality of cells communicate information signals between one another using at least one base station and code division multiple access (CDMA) spread spectrum type communication signals. The base station is included in a first of the cells and has a transmitter from which information is transmitted to subscriber units over at least one communication channel. The disclosed method includes the step of determining a first composite signal energy associated with signal transmission from the base station transmitter over a first set of simulated communication channels. The simulation method further contemplates estimating a first average data rate for the first composite signal energy. Signal power transmitted over the one communication channel is adjusted in accordance with a first interference signal which is based on the first composite signal energy and first average data rate. In a preferred implementation, a determination …
