Software defined radio (SDR) is an exciting merger of digital signal processing and wideband radio hardware. In this lab, the base band signal processing techniques of OFDM at the transmitter end (waveform encoding, source encoding, channel encoding, encryption, IQ mapping, IFFT, Serial to Parallel/Parallel to serial conversion, and pulse shaping) and at the receiver end (synchronization, carrier frequency/ symbol time offset correction, channel estimation, channel equalization, channel decoding, decryption, source decoding and waveform decoding) are done with the help of Labview Communication Suite software to generate base band modulated waveform. The base band modulated spectrum is shifted to high frequency pass band spectrum and becomes high frequency RF signal which is more suitable for transmitting it in wireless medium. This process is achieved with the help of hardware which consists of high speed FPGA.
