Method and apparatus to increase the diversity order for a multi-carrier FDM system

A base station transmitter of a multi-carrier frequency division multiplex (MC-FDM) system, comprising at least two transmit antennas, and circuitry to provide at least two MC system frequency sub-carriers to different ones of the at least two transmit antennas for transmission to a mobile station receiver through a channel, the circuitry providing, to at least one of the at least two transmit antennas, fewer than all of the at least two MC system frequency sub-carriers.

A method to increase a diversity order of a multi-carrier frequency division multiplex (MC-FDM) system, comprising:

• providing at least two transmit antennas;
• and
• allocating at least two MC system frequency sub-carriers to different ones of the at least two transmit antennas.

A computer readable data storage medium storing program instructions that direct a data processor to increase a diversity order of a multi-carrier frequency division multiplex (MC-FDM) system having at least two transmit antennas, the instructions causing the data processor and system to perform operations of:

• allocating at least two MC system frequency sub-carriers to different ones of the at least two transmit antennas;
• and
• transmitting the allocated sub-carriers towards a receiver.

Apparatus to increase a diversity order of a multi-carrier (MC) system, comprising at least two transmit antennas and means, coupled to said at least two transmit antennas, for providing at least two MC system frequency sub-carriers to different ones of the at least two transmit antennas.

A multi-carrier (MC) transmitter apparatus, comprising at least two transmit antennas and means, coupled to said at least two transmit antennas, for providing at least two MC system frequency sub-carriers to different ones of the at least two transmit antennas for transmission to a channel, said providing means providing, to at least one of the at least two transmit antennas, fewer than all of the at least two MC system frequency sub-carriers.
