802.16 Compliance Testing

 

WiMAX 802.16 2004 OFDM PHY/Overview

Mathematical models of 802.16-2004 (OFDM PHY layer) available.

Main module

Front panel for selecting parameters for running the transceiver such as data rate , channel model, number of packets .etc for simulation
 

WiMAX 802.16 2004 OFDM PHY Transmitter module

Complete transmitter functionality of the PHY layer.
 

WiMAX 802.16 2004 OFDM PHY Receiver module

Complete receiver functionality with front end algorithms like channel estimation, timing synchronization, frequency synchronization, phase correction etc.
 

WiMAX 802.16 2004 OFDM PHY Impairment module

Allows the user to add impairments such as AWGN, frequency offset, channel models, I/Q imbalance etc.

Each functional block is implemented as a separate function file and is called by the main module during execution.

The model provides for the facility to visualize the performance related parameters such as:

Constellation plot
Power spectrum (Baseband)
TX power
Eye diagram
CCDF
EVM
There is also a utility to perform the PER simulation for various channel impairments/SNR.

The code is completely visible and the user can drill down to each function.

This model has all the transmitter and receiver functionalities.

The channel models available for 802.16 (WiMAX), are SUI channel model 1 to 5. The current 802.16 model supports OFDM, and does not support multiple antennas as of now, 802.16e SOFDMA will be available soon.

Performance plots of PER vs. SNR for each standard/data rate /modulation scheme under various channel impairments will be provided on request.
