Abstract


The development of science and technology has brought rapid changes to people's life, people demand for high data rate promoted the rapid development of the personal mobile communication technology. Now the third generation mobile communications, has entered the commercial stage. In order to improve the system performance, reduce operational costs, the need for base station downlink link business reuse in system design and implementation of the improvement and optimization. Reuse system this paper analyzes the down link business demand, downlink link business multiplexing system architecture is given, and the specific business reuse process is analyzed and the main control process, and the implementation. In refer to the literature, based on the algorithm for the high CPU utilization in agreement such as CRC add, rate matching algorithm and the second algorithm is improved, and the improvement effect was tested. According to the characteristics of TMS320C6416 chip at the same time, the software was used to optimize technology of code is optimized, so as to improve the speed of data processing and carry users, and support in the future for more business data flow provides the possibility.
