Abstract  Abstract

the unit has a baseband processor connected with the memory and the modulation demodulation processor the two processors can communicate. modulation demodulation processor to signal into analogue signal and then removing burr of upconversion and filtering to form intermediate frequency signal is then amplified. the amplified intermediate frequency signal with the synthesizer signal obtaining radio frequency signal. the baseband processor generating a start signal according to the signal of the base station to determine the subscriber unit is transmitting or receiving mode. the system is started during the training mode for the known signal modulation demodulation processor and loopback signal so as to generate correction coefficient compensation frequency signal does not need of the variable.
