A RASE approach to acquisition in SSMA systems
暂无分享,去创建一个
The rapid acquisition by sequential estimation (RASE) method of DS/SS acquisition is applied to acquisition in a multiple-access channel (MARASE). In MARASE, a set of equations is developed which are nonlinear, noisy, and have a solution over a finite domain. An effective solution method is given which involves finding separate solutions to each equation, and then combining them using the error-correction capability of the maximal length spreading codes. Average acquisition time is analyzed and compared with simulation results.<<ETX>>
