• Indoor radio communications is an important component of the emerging personal communication systems service. It is also the basis for wireless local area networks. The indoor radio channel is characterized by fading multipaths as well as noise. Direct sequence spread spectrum (DSSS), with its inherent resistance to multipath interference is an attractive technique for this environment. To allow multiple users within the limited bandwidths available, code division multiple access is needed. This paper analyzes the performance of a DSSS scheme employing random orthogonal codes over fading multipath indoor radio channels using actual channel measurements from five different locations. A RAKE receiver is used to study the effects of power control, code length and receiver structure. The average probability of error as a function of signal-to-noise ratio or as a function of the number of simultaneous transmitters is used as the performance criteria.
