Method and equipment for processing data for transmission in a communication system of multiple channels using selective transmission channel

摘要

Method and equipment for processing data for transmission in a communication system using multi channel transmission the channel selective ". In the present invention techniques are described for selecting transmission channels used for data transmission and to process and transmit data through the selected transmission channels.The transmission channels available for use are separated into one or more groups, with each group including any number of channels.With selective channel transmission channels, only "good" in each group are selected (e.g., based on the received SNRs channel and a limit of SNR), the "bad" channels are not used, and the total power of the transmission available for the group is distributed (for example, uniform So nobly) only by good channels.Each group may also be associated with a respective coding scheme and modulation, and data for each group may be coded and modulated based on the scheme selected for the group. Improved performance is achieved by the use of only good channels in each group and coincidence of data processing to the selected channels for the capacity achievable by the channels.
