Spatial Multiplexing In A Cellular Network
US Patent:
6067290, May 23, 2000
Filed:
Jul 30, 1999
Appl. No.:
9/364146
Inventors:
Arogyaswami J. Paulraj - Stanford CA
Robert W. Heath - Hayward CA
David J. Gesbert - Mountain View CA
Robert W. Heath - Hayward CA
David J. Gesbert - Mountain View CA
Assignee:
Gigabit Wireless, Inc. - Mountain View CA
International Classification:
H04Q 728, H04B 7216, H04B 7185, H03D 322
US Classification:
370329
Abstract:
The present invention provides methods and apparatus for implementing spatial multiplexing in conjunction with the one or more multiple access protocols during the broadcast of information in a wireless network. A wireless cellular network for transmitting subscriber datastream(s) to corresponding ones among a plurality of subscriber units located within the cellular network is disclosed. The wireless cellular network includes base stations and a logic. The base stations each include spatially separate transmitters for transmitting, in response to control signals, selected substreams of each subscriber datastream on an assigned channel of a multiple access protocol. The logic communicates with each of the base stations. The logic assigns an available channel on which to transmit each subscriber datastream. The logic routes at least a substream of each datastream to at least a selected one of the base stations.
Methods Of Controlling Communication Parameters Of Wireless Systems
US Patent:
6298092, Oct 2, 2001
Filed:
Jun 2, 2000
Appl. No.:
9/585948
Inventors:
Robert W. Heath - Hayward CA
Arogyaswami J. Paulraj - Stanford CA
Arogyaswami J. Paulraj - Stanford CA
Assignee:
Iospan Wireless, Inc. - San Jose CA
International Classification:
H04B 706, H04B 708
US Classification:
375267
Abstract:
The present invention provides a method for controlling a communication parameter in a channel through which data is transmitted between a transmit unit with M transmit antennas and a receive unit with N receive antennas by selecting from among proposed mapping schemes an applied mapping scheme according to which the data is converted into symbols and assigned to transmit signals TS. sub. p, p=1. . . M, which are transmitted from the M transmit antennas. The selection of the mapping scheme is based on a metric; in one embodiment the metric is a minimum Euclidean distance d. sub. min,rx of the symbols when received, in another embodiment the metric is a probability of error P(e) in the symbol when received. The method can be employed in communication systems using multi-antenna transmit and receive units of various types including wireless systems, e. g. , cellular communication systems, using multiple access techniques such as TDMA, FDMA, CDMA and OFDMA.
