Digital RF

The goal of this work is to make an all digital wireless transceiver design. Front-end is designed using 2/3 sub-sampling technique where no synchronization or extra hardware is required to do carrier demodulation. In baseband 5x oversampling is used to overcome data and clock jitter and make data recovery to output a clear version of the digital signal. Even if the local receiver clock had phase shifting or frequency shifting compared to the ideal case, the sub-sampling technique can still work correctly as long as the shifting does not exceed a certain value as in the figure.
