Computer simulation of a direct sequence spread spectrum cellular radio architecture

A computer simulation study to evaluate the channel capacity of a direct sequence spread spectrum cellular radio architecture which is based on code division is described. The cellular radio architecture utilizes the processing gain provided by a wideband multipath RAKE receiver to suppress multicell/multiuser interference. As a result, the same piece of radio spectrum can be reused in every cell. We use a step-by-step approach to verify the basic idea behind the spread spectrum cellular radio architecture. Computer simulations are used to calculate the distributions of signal-to-reference ratio (SIR). From SIR distributions, one can easily calculate the channel capacity of the cellular radio architecture. Technical requirements to fulfil potential system performance are also discussed. Finally, an 800 MHz system example is given for cellular mobile radio telephone application. >
