The project is about DSP FILTERING. Please, take it into consideration ONLY if you have needed know-how (DSP FILTERING, ALL PASS FILTERS, DISCRETE WAVELET PACKET ANALYSIS FILTER BANK, DISCRETE WAVELET PACKET SYNTESIS FILTER BANK). The deliverables are 3 Matlab functions: 1. TX_FILTER() input: wave audio file input: watermark bit sequence output: watermarked wave audio file 2. RX_FILTER() input: watermarked wave audio file output: watermark bit sequence output: detection status (integer) 3. TEST() executes TX_FILTER() and RX_FILTER() one after the other. Detailed specs of function are described in [url removed, login to view], vers. 0.2; Detailed information about TX_FILTER is included in tx_filter_structure.m, vers. 0.4; General description of system and APF filters information are included in IEEEpaper.pdf. An example of audio_in is attached: [url removed, login to view]). A NDA will need to be signed. It will be provided.
Please, see attached files for specs.
