<p>An image transmission method capable of increasing the capacity of CDMA communication system and maintaining the quality of the image which uses sub-band coding and differential forecasting, by changing compressing ration and coding ration of the threshold according to the characters of the image, to keep the image quality not be changed. Employing either changing band-expand factor and altering the transmitting power accordingly or not changing the band-expanding factor but intermitted transmitting to increase the capacity of the CDMA system.</p> |
