Vishnu, I'm not sure what you mean by "which" wavelet transform. The critically-sampled wavelet transform or wavelet packet transform will yield the best results of the wavelet transforms if compression is the primary concern.
See the following functions in the Wavelet Toolbox, wdencmp, wpdencmp, and measerr

Try complex Morlet Wavelet
see http://www.bth.se/fou/cuppsats.nsf/all/315e9a86357c82d8c1257b0b002cc52e/$file/BTH%202013%20Ibeh.pdf
