Abstract :
We present our study of wireless image transmission over a CDMA link. To deal with the limited bandwidth problem of the wireless channel, we implement packetized zerotree wavelet (PWZ) coding scheme. For the error prone problem, we utilized the cyclic redundancy code (CRC) of CDMA links.
