Abstract: The testing and verification of CDMA cellular base stations requires a number of parameters to be measured. Many of these parameters are measured in the code domain where individual waveforms are extracted from a composite waveform through the use of orthogonal codes. A method and apparatus is described for measuring many code domain parameters using a modified code domain power measurement technique. The apparatus is comprised of a chip timing recovery circuit (46), a reference generator (78), a multiplier (60), various summers and absolute value operations, a memory (76), and a processor (90). In addition, a reference generator (78) for generating an improved reference waveform is described. Reference generator (78) is comprised of a Walsh code generator (200), an I channel PN sequence generator (202), a Q channel PN sequence generator (204), an XOR gate (206), and an XOR gate (208).
