چکیده
Complex wavelet Packet modulation CWPM system has gained special interest as compared with traditional WPM due to its positive features like shift insensitivity, good directionality, and presence of phase information. The objective of this paper is to design a baseband π/4-DQPSK CWPM transceiver and implementing it on FPGA hardware. The design uses 8point Discrete Wavelet Packet Transform DWPT/ Inverse Discrete Wavelet Packet Transform IDWPT as the core processing module. All modules are designed using VHDL programming language. Software tools used in this work are Altera Quartus II 9.1 and Altera ModelSim 6.5b. Cyclone III board EP3C120F780C7 is used as the target device.

متن کاملUsing WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
متن کاملImplementation of VlSI Based Image Compression Approach on Reconfigurable Computing System - A Survey
Image data require huge amounts of disk space and large bandwidths for transmission. Hence, imagecompression is necessary to reduce the amount of data required to represent a digital image. Thereforean efficient technique for image compression is highly pushed to demand. Although, lots of compressiontechniques are available, but the technique which is faster, memory efficient and simple, surely...
