Abstract
A channel estimation method in a Multiple Input Multiple Output (MIMO) mobile communication system having a plurality of transmission antennas and a plurality of reception antennas is provided. In a method of transmitting, by a transmitter, channel estimation signals for channel estimation at a receiver, the transmission antennas transmit the same channel estimation signals for a first frame transmission duration, and transmit predetermined channel estimation signals corresponding to the number of the transmission antennas for a second frame transmission duration.
Claims11
A method of transmitting, by a transmitter, channel estimation signals for channel estimation at a receiver in a Multiple Input Multiple Output (MIMO) mobile communication system having a plurality of transmission antennas and a plurality of reception antennas;
- wherein the transmission antennas transmit identical channel estimation signals for a first frame transmission duration, and transmit predetermined channel estimation signals corresponding to a number of the plurality of transmission antennas for a second frame transmission duration.
A method of performing channel estimation in a receiver in a Multiple Input Multiple Output (MIMO) mobile communication system having a plurality of transmission antennas and a plurality of reception antennas, the method comprising the steps of:
- receiving, from the transmission antennas, identical channel estimation signals for a first frame transmission duration and predetermined channel estimation signals corresponding to a number of the plurality of transmission antennas for a second frame transmission duration;
- classifying the channel estimation signals received for the first frame transmission duration and the channel estimation signals received for the second frame transmission duration according to transmission antenna;
- and
