Abstract

DC60 multi-user plans Which allows a certain number of users User group Or a shared sender using one or more Assigned channel In this invention The available channels are broken down into numbers. Subchannels with the same frequency range are in compliance with OFDM standards. The application says it is necessary to pass data at a specific transmission rate. Data transmitter Consider the minimum number of sub-channels and the maximum power initial reference point. (Or noise) for each sub-channel required to achieve the baud rate and select a group of channels. Subsets that respond to those requirements. Subchannels do not need to be adjacent to each other in the spectrum or to be affiliated in Same channel Once the transmitter has selected the desired number of subchannels, it will initiate transmission at the same time on these subchannels over the entire frequency range used by Those sub-channels Multi-user plans Which allows a certain number of users User group Or a shared sender using one or more Assigned channel In this invention The available channels are broken down into numbers.
