Title:
ワイヤレス無線ネットワークにおける分散型時空間符号化のための方法及び装置
Document Type and Number:
Japanese Patent JP5135337
Kind Code:
B2
Abstract:
A method and apparatus is disclosed herein for performing distributed space-time coding. In one embodiment, the distributed space-time coding is used for downlink communications in wireless radio networks. In one embodiment, the method comprises storing information-bearing sequence at two or more base stations in a group of base stations; and transmitting data corresponding to the information-bearing sequence from a number of base stations for receipt by a receiver of a user, where the number of base stations is not globally known a priori and indicates a diversity of order, such that the diversity of order M is obtained if a total of M number of antennas spread over multiple base stations transmit the information-bearing sequence, where M is an integer.
