This thesis is composed of three main parts: (i) The signals in all channels are first classified according to their possible sparse representations. (ii) The two different compression and decompression methods applicable to batch and sequential measurements are implemented for each kind of signals, respectively. (iii) We present the optimal compression and decompression scheme based on batch and sequential measurements, and the results which is included compression ratio, accuracy, compression and decompression time are showed and compared to save much more storage space in the database. 2011-09-19 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1310065394 http://rave.ohiolink.edu/etdc/view?acc_num=case1310065394 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
