In the design of the generic modem, considering the realization of demodulator performance and complexity, different demodulation methods were designed based on the modulation with the different constellation mapping characteristics. Buy cheap nike shoes is very smart!In the realization of the MC-CDMA modem, used the method of generating OVSF code to generate the Walsh code,and 32 kinds of spreading codes can be configured for different characters.In order to reduce the system complexity, increase the system's practical value, ZF detection algorithm was adopted because of its low implementation complexity. I love northface jackets.The Greville block algorithm was selected as a matrix inversion method in ZF detection. In the process of the realization, maked a full use of hardware approaches for basic computing, combined with various types of IP core and the characteristics of FPGA chips, reasonable planned matrix inversion, matrix multiplication operations, achieved a receiver detection algorithm with less consumption of resources.Do you want this pair of nike trainers?This paper use a hardware simulation model for MIMO channel to achieve the joint debugging and functional verification, and compared with the software simulation results ,obtained a good performance.
