MULTI-BAND TRANSMISSION SYSTEM
First Claim
1. A system, comprising:
- a transmitter device configured to separate data into a plurality of frequency bands, whereineach frequency band has an associated symbol time,each associated symbol time is a whole multiple of one half of a smallest symbol time of all of the frequency bands, andthe transmitter device includes;
i) a multiple input, multiple output (MIMO) processing block configured to multiplex the data into a plurality of spatial channels, andii) an analog front end configured to provide the data in the plurality of frequency bands and the plurality of spatial channels to a transmission medium.

Abstract
Signals transmitted via a plurality of frequency bands by a transmitter using respective sets of one or more transmit chains are received at a receiver device. The signals are processed at the receiver using a plurality of receive chains including using a set of first receive chains associated with a first frequency band, and using a set of one or more second receive chains associated with the second frequency band. A number of receive chains in the first set of receive chains is different than a number of transmit chains used by the transmitter device to transmit via the first frequency band. A number of receive chains in the second set of receive chains is different than a number of transmit chains used by the transmitter device to transmit via the second frequency band. MIMO processing is performed on outputs of the set of first receive chains.
