Abstract


On the basis of the third generation of short-wave communication network standard MIL-STD-188-141B 's shortwave multipath fading time-varying channels under the key technologies for high-speed data transmission , according to the protocol design to achieve high-speed data transmission burst waveform BW2 transmission and reception of programs. The shortwave channel is a typical variable parameter channel , limited bandwidth , multipath fading shortwave channel data transmission . Antijamming measure in accordance with the characteristics of the BW2 frame format , the receiver side can use the adaptive equalization processing . In this paper, based on the total program of research on the sending and receiving , focusing on analysis of the adaptive equalization principle , LMS, RLS algorithm , as well as a detailed discussion and analysis of adaptive equalization algorithm based on channel estimation and apply them BW2 receiver when the advantages and disadvantages , and the MATLAB simulation environment of the BW2 sending and receiving programs tested to verify the feasibility of the program , the performance reached the intended target . According to the results of the simulation , and finally on the DSP hardware platform assembly language BW2 waveform of transmit and receive module .
