Transmitter oriented code division multiple access system using a multi-user diversity in order to maximize throughput while providing users access fair

摘要

Of the transmitter oriented with multi-user diversity provided by distribution of the receiver, the distributed. I use the change of uncorrelated with respect to time in the state of the communication link between several users and transmitter common. With respect to time, the larger the change in the quality of a particular link, the greater the increase in total system throughput to be provided large. (Or scheduler metric) scheduler single metric represents the instantaneous quality of the communication link between the transmitter and each user with respect to the average quality of the link. Alternatively, the scheduler metric represents the instantaneous channel conditions with respect to the average data throughput for the channel. You want to use the scheduler metrics in order to compare directly with the desirability to allow channel access to each other, the desirability to allow each channel access transmitting station common. The user with a link that has a scheduler metric of maximum, are provided access to the channel.
