FPGA based fast complex wavelet packet modulation (FCWPM) system

  • This paper presents an efficient design and implementation of a complex wavelet packet modulation (CWPM) multicarrier communication transceiver using an FPGA platform. A fast algorithm already proposed for high data rate WPM systems has been applied to CWPM systems for speed enhancement. The theoretical performance of the computation algorithm is analyzed. The design uses 16-point Fast Wavelet Packet Transform/Inverse Wavelet Packet Transform (FWPT/IFWPT) of the Haar family as the core processing module. All the proposed fast CWPM (FCWPM) system modules are designed and implemented using VHDL programming language. Software tools used in this work include Altera Quartus II 9.1 and ModelSim Altera 6.5b. A Cyclone III board is used for the implementation. The hardware simulation results show that the use of fast Haar wavelet packet transform algorithms to implement complex wavelet packet modulation systems significantly increases its speed as compared with direct implementations.
