Enhancement of the channel propagation matrix order and rank for a wireless channel

摘要

Enhancement of wireless Channel Order and rank (ECHO) systems and ECHO repeater devices for enhancement of a wireless propagation channel for point to point or point to multipoint radio configurations are disclosed. The enhancement may be used for MIMO communications channels. Aspects support a richer multipath environment to increase the rank of the channel propagation matrix and/or to increase the magnitude of the coefficients of the propagation matrix between two or more radios. Such enhancement is applicable to backhaul radios in terms of increased range or in the number of supportable information streams. The installation, provisioning, optimization, control, monitoring, and adaptation of such devices within a network of backhaul radios is also disclosed. Wireless links and control between IBR and ECHO devices, and between ECHO devices and other ECHO devices, are also disclosed.

1. A wireless communication repeater device for the enhancement of a multiple input multiple output (MIMO) communication channel between a first and a second radio comprising:
a receiver for receiving a plurality of first information streams from a first radio, the plurality of first information streams each having one or more embedded first control signals; a transmitter for transmitting a composite signal to the second radio, wherein the composite signal comprises at least one of the plurality of first information streams and one or more embedded second control signals, the one or more embedded second control signals respectively associated with one or more of the plurality of first information streams; a channel filter for channel filtering a signal comprising the at least one of the plurality of first information streams and at least one of the one or more embedded first control signals; a detector for performing detection of at least one of the one or more embedded first control signals; a repeater device controller for enabling the transmitter based upon said detection; a demodulator for demodulating at least one of the one or more embedded first control signals to determine first control information; a modulator for generating one or more second control signals; and a coupler for combining the one or more second control signals respectively with a signal comprising the at least one of the plurality of first information streams to produce the composite signal that comprises the at least one of the plurality of first information streams and the one or more second embedded control signals, wherein the one or more second embedded control signals are usable by the second radio to determine second control information and to determine information within said second control information for forwarding to the first radio; wherein the wireless communication repeater device is for enhancing the performance of the MIMO wireless communication channel between the first radio and the second radio based upon an adjustment of parameters associated with one or more of: i) the wireless communication repeater device based upon information within the first control information; and, ii) the first radio based upon information within the second control information and, wherein the adjustment of parameters is configured to set a signal level of one of the plurality of the first information streams at the wireless communication repeater device relative to signal levels of one or more of the other first information streams of the plurality of first information streams based on a predetermined ratio.
