摘要： Provided are a transmitting apparatus and a transmitting method in a multiple input multiple output system. A power allocation controller includes a block Tomlinson-Harashima precoder (BTHP) that precodes and outputs data to be transmitted to each user in a nonlinear scheme. The BTHP removes and outputs inference signals from data for each user based on the channel information that is fed back from the users. The data for each user output from the BTHP are allocated with power by the power allocation controller. The power allocation controller calculates power allocation parameters so that receiving minimum distances at receiving ends for each user that receive data through the MIMO antennas are the same, and allocates the calculated parameters to data for each user.

摘要： A base station calculates the number of terminals which have transmitted messages at ith frame, and calculates the number of messages to be transmitted at (i+1)th frame by using the number of terminals which have transmitted the messages in the ith frame. The base station calculates a transmission probability by using the number of messages to be transmitted in the (i+1)th frame and the number of random access slots, and transmits the number of messages to be transmitted in the (i+1)th frame and the transmission probability to the plurality of terminals. The base station receives a message transmitted by a pertinent terminal, whose number of messages to be transmitted in the (i+1)th frame is greater than the number of random access slots, among the plurality of terminals, according to the result obtained by comparing the transmission probability and a random number.
