Traditional algorithms of HF burst signal detection and synchronization acquisition usually can't work well under low signal noise ratio (SNR). Aiming at the character of HF channel, a reliable synchronization acquisition scheme for HF channels based on spectrum analysis method was obtained by modulated m-sequences pilots to get some dispreading gains. The(More)
In order to solve the problem of the distance estimation of the infrared passive system, a distance estimation algorithm is proposed based on the optimal estimation theory of structure stochastic jump system. Considered the rapidity and the limit of the internal storage capacity of the algorithm, a simplified algorithm is derived. And the ability of the(More)
