Abstract

A software radio system based on a PC and a computer network can enjoy the advantage of greater flexibility. However, it puts great pressure on the processing ability of the PC. So effective approaches for signal estimating and data stream decoupling are developed to reduce the necessary processing time and lessen the use of computing resources. A task scheduling. mechanism is carefully designed to make reasonable use of the capacity of the CPU. The approaches and the task scheduling mechanism are introduced. They have certain significance for software radio systems
