This repos contains the implementation of IEEE 802.16 (i.e. WiMax) OFDM-based transceiver system. This is stored in 3 separate parts, i.e. transmitter (TX), receiver (RX) and transceiver (SYS).
Each part includes implementation files stored in MY_SOURCES and IPCORE, 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_802_16.v, OFDM_RX_802_16.v and OFDM_SYS.sch are the top modules of transmitter, receiver and transceiver systems, respectively.
IPCORE contains the configured files of IPCores instantiated by impelemented systems. The IPCores are generated using ISE Design Tool.
MATLAB contains matlab files that simulate 802.11 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.
This implementation is presented in the papers below:
