The frequency domain electric transmitter and receiversynchronization electrocircuit has been designed. It is concluded that the GPS time synchronization is feasible in this instrument.
There are many key technologies about the single-user detection, such as synchronization between receiver and transmitter, channel estimation and diversity.
单用户检测中的关键技术很多，主要有接收端和发送端的同步，信道估计和分集等。
