Abstract
A base station is in a spread spectrum code division multiple access (CDMA) communication system which co-exists with a microwave system. The microwave system selectively utilizes various microwave frequencies within a selected range of frequencies. The base station generates a plurality of spread spectrum CDMA data signals using pseudo random chip code sequences. The spread data signals encompass the selected range. The base station notch filters the spread data signals at microwave frequencies within the selected range used by the microwave system. The notch filtered spread data signals are transmitted to personal communication network units.
