Method for controlling Transmission Power in a Multichannel System, transmitting end and receiving end

摘要

A method for controlling Transmission Power in a Multichannel System, comprising: receiving (E110) Through Channel n, N signals sent by a Transmitter End,Where a iu00e9sima Signal at the ITH n signals are sent in a Transmission channel in n channels transmitted by the transmitting End.Each signal in the N signals comprises a Channel estimation sequence, N is a positive integer, integer, N = 2, e i = 1,2,...,N (E120); determining a total reception Power of a reception channel in the ITH Channel (EI30); determining a Channel Matrix H according to the sequence of Channel re estimationCibida (E140); determining a Power reception of the ITH helpful reception Channel according to the channel Matrix H and the total reception Power of the ITH Channel receptionWhere the power of the ITH helpful reception reception Channel indicates a Power reception, which is responsible for the iu00e9sima SignalIn the ITH Channel total Power reception reception; determine (E150), according to the channel Matrix H and a Signal Strength that is required by the communication of a Single Channel.A reception Power required by the ITH Channel reception (E160a); and sending a message to the Extreme Power adjustment if the transmitter Power of the ITH Channel receiving useful recepDoes not match the Power required by the ITH Channel reception receptionSo that the end Transmitter adjusts a Transmission Power of iu00e9sima Signal according to the message of Power adjustment.
