Original Abstract

The modem for data transmission over telephone channels that complies with the UIT V.34 recommendation is a device with a very complex structure. An important component in the realization of the conversion of input bit flow to output signal is the application of trellis code in order to secure information about the phasor position against errors. This position is frequently changed due to the phase jitter in the communication channel. Protection via anti-error encoding is used in other modems too. But the code used in the V.34 modem is quite different. That is the reason why we are interested in this code. The text below gives a brief description of this code.

Key words in English

phasor position, phase jiter, error position, anti-error coding.
