发明名称 Data transmission method for a mobile communication system
摘要 This invention provides a mobile communication system which expanded the operation limitation of the heretofore adopted mobile communication systems and improved the spectrum efficiency greatly. A data transmission method for use in the mobile communication system of the present invention includes means for channel pluralizing by which to expand the Shannon limit and means for interference reduction by which to expand the interference limit. More specifically, a transmitting module comprises M units of modulators and L units of transmitting antennas, generates L units of signals by multiplying M units of modulated signals by a complex matrix consisting of M×L units of elements, and transmits the L units of signals from the L units of transmitting antennas.

主权项 1. An information processing device comprising: a modulator which generates a plurality of modulation symbols; a converter which converts the plurality of modulation symbols into M units of signals (where 2≦M); a processor which performs beam forming of the M units of signals by using a complex matrix whose size is L×M, and outputs L units of beam formed signals (where 2≦L).
