In the field of wireless communication, signals have to be received from multiple stations simultaneously. To achieve this, a separate set of dedicated resources for each station is used. In order to avoid the costly upgradation and multiple hardware resources, a Software Defined Radio receiver architecture is proposed in this paper for RF applications. QPSK modulation scheme is used for data communication. In the proposed concept, single channel is utilized to act as multiple channels using Time Division Multiplexing. A proof-of-concept experiment has been realized on a testbench using Verilog HDL and MATLAB. The simulation result validates the proposed architecture.
