CONSTANT DATA RATE SPEECH ENCODER FOR LIMITED BANDWIDTH PATH |
摘要 |
The transmission of analog communications signals having varying frequency content, such as voice signals, over limited bandwith or data rate communications channels is accomplished by varying the amount of frequency data transmitted to maintain a constant rate of data transmission. A signal, such as a speech signal, is extracted and encoded (16), transmitted over a limited-data-rate path (18) and is decoded (20) and synthesized (22) at the receiving end.
