Multi-Standard OFDM-based transmitter for cognitive radios.

This repos contains the implementation of Multi-Standard OFDM-based transmitter that supports generating the transmited signals of 802.11, 802.16, 802.22. The operating standard of transmitter is dynamically switched by changing the configuration in run-time.

This repos includes implementation files stored in MY_SOURCES, and simulation golden model stored in MATLAB.

MY_SOURCES contains hdl files using verilog to implement the sub-modules (.v) of systems and to make a testbench files (_tb.v). There are some pre-computed cofficient sets defined by the standard (e.g. preamble) are stored in '*.txt' files. OFDM_TX_CR.v is the top modules of transmitter.

MATLAB contains matlab files that simulate OFDM signals as a golden model for implementation. The matlab files are also used to generate test vector for testbench and verify the output files from testbench.
