ENCODING MODE CONTROL METHOD AND DECODING MODE DETERMINING APPARATUS |
摘要 |
<p>In a digital cellular radio communication system, a base station selects a speech/channel encoding mode based on measurements of the local radio environment. The mobile station determines the selected mode by trial decoding possible modes to find the most probable mode and uses the same mode for transmission to the base station on the return link. The coding gain/loss obtained by this mode switching may be used to adjust the output power of transmitters, thereby reducing the overall interference level in the system.</p> |
