Implementation of a WCDMA channel emulator on a Xilinx Virtex-II FPGA
Tim Hannon · 2004
The paper investigates channel modelling for the WCDMA time-varying, multipath fading channel. It examines the necessary trade-offs between the accuracy of the model and its suitability for hardware implementation. The WCDMA channel emulator is implemented on a Xilinx Virtex-II FPGA. Finally, the performance of the fixed point hardware based channel model is compared to floating point Matlab simulations. One objective of the work is to provide a useful but inexpensive method of generating a channel model, which accurately predicts the performance of a wireless channel and provides realistic output signals to assist with the testing and development of WCDMA receivers.
