This paper evaluated the practical limits of Software-Defined Radio (SDR) devices and the impact of virtualization on receiving and transmitting samples, particularly in an Orthogonal Frequency Division Multiplexing (OFDM) application. The study tested the sampling rate at which the USRP B200 and N200 devices can transmit and receive samples.

Software Defined Radio (SDR) or Software Radio is one of the most important technologies for the modern wireless communication system. SDR is a radio which can tune to any frequency band, implement different modulation and demodulation schemes and different standards in the same device by using reconfigurable hardware and powerful software. SDR provides flexible, upgradeable, multi-standard ...
