Abstract: A data transmission processing method is provided for a communication device. The method includes calculating a packet-error-rate level parameter after a basic adjustment process, if it is detected that the basic adjustment process is performed on a modulation and encoding policy of a sending end during a data packet transmission process; obtaining the packet-error-rate change information by comparing a packet-error-rate level parameter before the basic adjustment process with a packet-error-rate level parameter after the basic adjustment process; and performing an upgrade adjustment process on the modulation and encoding policy that is adjusted by the basic adjustment process, if the packet-error-rate change information satisfies a preset adjustment processing condition.

Abstract: A data transmitting method includes generating multiple channels of encoded data by encoding same data to be encoded according to a plurality of bit rates and selecting encoded data to be transmitted from the multiple channels of encoded data according to a channel bandwidth of a transmission channel. The encoded data to be transmitted is one of the multiple channels of encoded data that matches the channel bandwidth.
