ECE 734 Final Project Proposal

چکیده
The structure and algorithm of IDFT DFT, the conventional method used in modulation/demodulation process in OFDM system, has matured today. Researchers have developed new transforms in an effort to replace this traditional structure, such as DHT-based structure (Discrete Hartley Transform) and DWT-based (Discrete Wavelet Transform) structure. In this project, all three structures will be implemented in MATLAB to acquire their BER (Bit Error Rate) performances, and the results will be compared and analyzed along with other two aspects, hardware performance and hardware complexity to gain a complete view of their advantages and disadvantages. Background and Prior Work In OFDM system, IDFT DFT hardware in the transceiver is conventionally designed jointly to carry out IDFT and DFT functions for transmission and receiving processes, respectively. To date, the development of IDFT DFT structure and algorithm used in the modulation/demodulation process has reached its maturity. In the last few decades, researchers have proposed several alternative transforms to replace IDFT DFT, such as DHT (Discrete Hartley Transform) IDHT (Inverse Discrete Hartley Transform) and DWT (Discrete Wavelet Transform) IDWT (Inverse Discrete Wavelet Transform). Past research has individually compared one of the many transforms to the DFT-based structure on one or two of the performance aspects, such as BER performance, hardware performance, or hardware complexity. For example, the DHT-based structure in research [1] generates similar BER performance and lower complexity. A DWT-based structure in research [2] shows better BER performance under certain conditions. A lot of effort [3] [4] [5] was put into implementing the hardware to lower the complexity or increase the operating speed.

After doing a literature survey on the DFFS algorithms ([1] ~ [6]) proposed in recent years (after 2000), we select the algorithm presented in [1] to be implemented in our project. Compared with other algorithm we study in the literature survey, the selected algorithm is able to achieve highest clock frequency and spurious free dynamic range (SFDR) while requires a modest implementation complex...
متن کاملFinal Project Specifications
The final project in ECE 403 can be in any subject related to audio or audio engineering. The project should consist of three components: a scholarly component, a design component, and an experimental component. How much you put in to each of these components will depend on the particular project you choose, and some tradeoff is possible, but you should make sure that each component makes it in...
