[Abstract]:In order to efficiently run the LTE communication system on the digital signal processor with superscalar and VLIW dual-mode hybrid architecture, the physical layer model of LTE is analyzed, and the performance bottleneck in the system is found. Aiming at the performance bottleneck, a method of hardware / software co-design is proposed to optimize the key algorithm of LTE. The OFDM transmitter and channel estimation module are selected to focus on the analysis and optimization from the algorithm level, and from the processor level to optimize, including the improvement of instruction set and the adjustment of processor structure. The experimental results show that this method is effective and feasible, and the processor has good performance on which the LTE system can run efficiently.
