TRANSMIT AND RECEIVE APPARATUS AND METHOD
First Claim
1. An apparatus comprising a plurality of antennae, one or more receiver chains, non-volatile memory and a signal processor, the non-volatile memory storing instructions for executing by the processor, the processor, when executing the instructions configured to:
- determine a first threshold value;
apply, to each of a plurality of signals individually received through different antennae, windowing in the frequency domain, and to determine as windowing result, for individual window frequency positions, a number of data values above the first threshold;
merge the windowing results determined for the individual signals for corresponding windowing positions; and
identify as noise bands spectral areas with merged windowing results above a second threshold;
transmit and/or receive signals in spectral bands outside of the noise band spectral areas.

Abstract
According to an embodiment an apparatus comprises a plurality of antennae, one or more receiver chains, non-volatile memory and a signal processor. The non-volatile memory stores instructions for executing by the processor. The processor, when executing the instructions, is configured to determine a first threshold value, apply, to each of a plurality of signals individually received through different antennae, windowing in the frequency domain, and to determine as windowing result, for individual window frequency positions, a number of data values above the first threshold, to merge the windowing results determined for the individual signals for corresponding windowing positions, to identify as noise bands spectral areas with merged windowing results above second threshold and to transmit and/or receive signals in spectral bands outside of the noise band spectral areas.
