APPARATUS AND METHOD FOR GENERATING EFFECTIVE SIGNAL TO NOISE RATIO PER STREAM IN A MULTIPLE INPUT MULTIPLE OUPUT WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus and method for generating an effective Signal to Noise Ratio (SNR) per stream in a Multiple Input Multiple Output (MIMO) wireless communication system is disclosed. The apparatus includes a selector, a calculator, a generator, and a decider. The selector selects effective streams among whole streams. The calculator calculates a relative SNR rate between the effective streams. The generator generates an equation having as a solution an SNR of a first effective stream. The decider decides an SNR per effective stream using the solution of the equation and the relative SNR rate.
