Abstract


Shortwave communication advantages due to its not easy to be destroyed in military communication plays an important role , However the shortwave channel discoloration dispersion characteristics , and multipath propagation effects , greatly reduce the reliability of the communication . This article as a starting point , focus on channel estimation algorithms and data detection technology in the U.S. military standard MIL S TD 1 88 1 10A basis of hardware platform designed to do in-depth research . First, according to the physical characteristics of HF channel , given the equivalent baseband model . The classic RLS channel estimation algorithm performance analysis , and the shortwave channel features fast RLS algorithm , the algorithm has low complexity and can estimate the channel in real time . Secondly , according to the basic linear data detection algorithm , simulation fast nonlinear data detection algorithms and solution Finally, a detailed description of the system hardware platform based on the DSP TMS320C6713 design , module interfaces and debugging process code optimization algorithm , gives the idea of the direction of further research .
