Abstract

Systems and methods that provide channel bonding in multiple antenna communication systems are provided. In one embodiment, a method for signal transmission over a plurality of antennas of a transmitter may include, for example, one or more of the following: demultiplexing an input signal into a plurality of signal components; assigning each of the signal components to one of a plurality of logical channels; weighting each of the signal components with transmit baseband weight values; combining ones of the resultant weighted signal components to form a plurality of transmit weighted signals, each of the plurality of transmit weighted signals being assigned to one of the plurality of logical channels; and combining groups of the plurality of transmit weighted signals to form a plurality ofoutput signals capable of being used to generate a plurality RF output signals.

Description

technical field [0001] The present invention relates to a communication system, more specifically, to a system and method for channel bundling in a multi-antenna communication system. Background technique [0002] Most current wireless communication systems consist of nodes equipped with a single transmit and receive antenna. However, it is predicted that the performance, including capacity, of many communication systems will be substantially improved through the use of multiple transmit and / or multiple receive antennas. This antenna configuration forms the basis of "smart" antenna technology. Smart antenna technology combined with spatio-temporal signal processing can be used to reduce the harmful effects of multipath fading of input signals and suppress interfering signals. In this way, the performance and capacity of existing or developing digital wireless systems (eg, CDMA-based systems, TDMA-based systems, WLAN systems, and OFDM-based systems such as IEEE 802.11a / g) w...
