METHOD AND APPARATUS FOR DETERMINING POWER ALLOCATION IN A MIMO COMMUNICATION SYSTEM

摘要

In a MIMO communication system 100 with a limited power for each antenna, a method for determining the allocation of empty energy levels in each OFDM frequency bin on each transmit antenna, an apparatus is provided, and a processor 420. The estimated value of the solution vector containing elements for each OFDM frequency bin allocated to bin energy level is determined by the respective antennas. In addition, an error function based on the determined solution vector is determined. Size error is determined based on the determined error function. Size error is compared to the error threshold value. The processor 420, if the error magnitude is smaller than the error threshold value, by using the elements for assigning the vacant energy level receives an estimated value of the solution vector. ; MIMO communication system
