We investigate optimum rate assignment scheme maximizing network throughput on the downlink of a multirate CDMA wireless network. Systems employing orthogonal variable spreading factor (OVSF) codes as well as systems employing multiple codes have been studied. Our objective is to maximize the network throughput under constraints on total transmit power,(More)
In mobile wireless data communications, it is very important to reduce the average energy consumption while maintaining a target frame-error-rate (FER) and frame latency. These goals can be achieved by means of Hybrid–ARQ (re)transmission power control. By allocating different symbol energy for each (re)transmission, the average energy consumption can be(More)
