Throughput of a multihop packet CDMA network with power control

In this paper we have modeled a slotted packet CDMA network with fixed repeaters to analyze the system throughput. Six repeaters forming a hexagon have been placed in the standard cellular network to reduce the total power consumption and intercell interference. In each slot, a repeater is either in transmit or receive mode. The effect of different mode selection timing schedules on throughput has been modeled. Repeaters and base station selection regions are defined in a way to limit the maximum interference from terminals. In this model, throughput is calculated as a function of the number of packets transmitted to the base station and interference, which is due to the data transmissions to repeaters, as well as the background noise. A Chernoff bound approach has been used as a general method of finding the upper limit for interference in a network partitioned in any shape. It is shown that for the same cell size and power consumption, the network with repeaters can dramatically increase the system capacity
