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.
