The 2D spreading based communication systems implementation using USRP

This paper deals with issues related with implementation of Variable Spreading Factor Orthogonal Ferquency and Code Division Multiplexing (VSF-OFCDM) systems using Universal Software Radio Peripheral (USRP). Comparison of simulated and with USRP hardware achieved results of VSF-OFCDM systems with various 2D spreading factors (SF) are being done. Simulation of complete communication chain is being done but only the transmitter part was implemented and investigated using USRP.
