urbo编译码器仿真平台的设计

his paper gives the realization of Turbo simulation platform using Visual C++6.0 and the function and design of each module of the platform. This simulation platform consists of five modules . in which the main modules are the Turbo coder module, the channel simulation modules and the Turbo decoder module. In Turbo coder module , the coder parameter can be setted for checking the effect of parameter. The channel simulation module can model various channel, such as the AWGN(Additive White Gauss Noise) channel, the Rayleigh fading channel etc. the Turbo decoder uses the Log-MAP as the decoder algorithm. Turbo Codec is simulated mostly in Matlab before, and the speed of Turbo Codec is slow, so as to it cannot process the huge volume of data quickly and conveniently. We utilize the strong user’s interface developing power of VC++, to design the Turbo Codec simulation platform in VC++ to be visible and more convenient, the simulation of algorithms is of much higher speed.
