MULTI-ANTENNA BROADCAST TRANSMISSION METHOD INCREASING DEGREE OF FREEDOM WITHOUT FEEDBACK OF CHANNEL STATE INFORMATION AND AT LEAST ONE ANTENNA RECEPTION METHOD

摘要

PURPOSE: A broadcast transmitting method using a multi antenna improving degree of freedom without feedback of channel state information and a receiving method using at least one antenna are provided to improve degree of freedom without feedback of the channel state information, when a transmitter having a multi antenna communicated with a receiver having at least one antenna. CONSTITUTION: A transmitter accesses a channel table including a plurality of complex elements stored in a memory in advance (1010). The transmitter selects specific complex elements among the plurality of complex elements included in the channel table so that a valid channel between oneself and at least two receivers becomes a staggered block fading channel (1020). The transmitter generates a transmission signal by using each of the selected complex elements and symbols (1030). The transmitter transmits the transmission signal by using the multi antenna installed in oneself (1040).
