GSM — Regular Pulse Excitation - Long Term prediction
Information on Regular Pulse Excitation - Long Term prediction
The GSM voice coder compresses digital voice signals arriving at
8000 samples / s to a 13-kbit / s signal.
The
GSM speech compression algorithm is Regular Pulse Excitation - Long
Term prediction - Linear Predictive Coder (RTE/LTP). The compression
involves mapping input blocks of 160 speech samples to encoded
blocks of 260 bits. This process is reversed in decoding
(i.e. mapping input blocks of 260 bits to output blocks
of 160 reconstructed speech samples.)
