A simple design of a complementary filter is presented for performance measurement of an IS-95 code division multiple access (CDMA) wireless communication system. The complementary filter is required to meet the design requirements, which are specified in IS-97 document. The purpose of employing the complementary filter in a test-equipment is to remove inter-chip interference (ICI) introduced by the base station (BS) transmit-filter and the transmit-phase equalizer. Five window functions, which do not affect the desirable response at the proper sampling times, are applied to the desirable output. It is found that the complementary filter with Kaiser window meets all requirements specified in IS-97 and has the smallest number of the filter coefficients among all windows considered in this paper. Therefore, the complementary filter with the Kaiser window is recommended for implementation of the IS-95 system measurement
