SOUND DATA TRANSMITTING METHOD IN CHANNEL MODEM FOR SATELLITE COMMUNICATION SYSTEM

摘要

PURPOSE: capable of subtracting transmission data and improving the processing time for the channel modem satellite communication system of sound sending method passes through Transform Acoustic data with the speed for transmitting data, shrinking code is to be transmitted to every predetermined space and generate the part for happening suddenly and residue voice data being utilized to pass through different from coding, is provided. CONSTITUTION: the channel modem of the sending method of data is used for satellite communication system, the described method comprises the following steps:: compression transmission voice data; The transmission voice data of multiplexed compressed; Transformation, coding voice data are multiplexed to zero code, each predetermined space; Burst is generated in addition to zero code with voice data is in coding voice data; The train of pulse generated with modulation and transmission.
