Blind Asynchronous Multiuser Detection in Impulsive CDMA Channel
In this paper we propose a new method in multiuser detection for asynchronous CDMA channel in which we use a series of Training bits to obtain the characteristics of the channel.Each of the samples of a spreaded bit experiences different noise parameters due to the perodic nature of signature wave forms.As a result, one must calculate noise probability density function (pdf) for each bit position which is done here through the Train Phase. After fmishing the Train Phase, the process of detecting bits is almost real time. As we estimate the channel parameters,this method can be assumed a Blind one.
