Project description:
"i need to create a wireless link, in which through matlab code i'll transmit my message to USRP N210 and receive from same USRP, and recovered message. Modulation used format can be QPSK. following steps should be followed. Recommended steps for SW development
1.
Convert your message to bits
2.
Form the symbols: QPSK, 16QAM…
3.
Arrange symbols to frames and add preamble symbols
4.
On the Rx side do the opposite: extract your message bits from the symbols
5.
Transmit a message and make sure you can receive it
6.
Up-sample and pulse-shape the symbols in the Tx, in the Rx Detect the frame start and extract the preamble symbols (you will need them later onfor fine frequency correction).
7.
Filter and downsamplethe received signal at the Rx.
8.
Apply frequency offset! Do coarse frequency correction. Try to again detect the frame start.
9.
Use the extracted preamble symbols to find the residual frequency offset and phase offset.
10.
Correct the received Rx symbols for the residual frequency offset and phase
11.
Extract the message.
12.
Do the same using the USRP where Tx and Rx are connected witha cable.
13.
Try with your real HW and a common LO source
14.
Try with your real HW and 2 LO sources
