Abstract
Disclosed is a method for optimizing forward link coverage in a spread spectrum communication system, e.g., CDMA system. Spread spectrum test communication signals are transmitted from a base station at a known power level, using an antenna having a known beam direction. Orthogonal channel noise is simulated in order to model noise generated by wireless communication traffic existing in an operational communication system of many subscribers. A mobile station receives the test communication signals in a specific region of a cell, and measures signal quality parameters, e.g., RSSI, Ec/Io and a forward frame error rate (FFER), from the received signals and simulated noise. The measured signal quality parameters are compared to respective criteria. Each region is designating as being satisfactorily covered by the base station if the measured signal quality parameters substantially satisfy the criteria. Otherwise, base station equipment is adjusted to modify the transmission of the test communication signals, and the process is repeated.
