Abstract
Embodiments of the present invention can be used to enhance signals in a peer-to-peer radio system, such as a two-way radio system. In one embodiment, the invention includes receiving a communications signal on a channel from a remote radio at a radio using a plurality of antenna elements, such as an antenna array. The received communications signal includes a squelch code. The radio detects the squelch code, and enhances the received communications signal using the squelch code.
Claims28
-38. (canceled)
A method comprising:
- receiving a communications signal on a channel from a first transmitter at a receiver using a plurality of antenna elements, the received communications signal including a squelch code;
- receiving an interfering signal not including the squelch code on the same channel from a second transmitter at the receiver, receipt of the interfering signal at least partially overlapping in time with receipt of said communications signal;
- detecting the squelch code;
- and
- enhancing the received communications signal using the squelch code, wherein enhancing the received communications signal comprises mitigating interference caused by the interfering signal.
A method comprising:
- receiving a plurality of versions of a communications signal by using a plurality of antenna elements, at least one version of the communications signal including a training signal;
- employing the training signal to determine a spatial processing strategy for combining at least a portion of the plurality of versions of the communications signal.
An apparatus, comprising:
- a plurality of antenna elements to receive a plurality of communication signals;
- and
- a combiner module coupled to at least one of the antenna elements to determine a set of receive spatial processing weights using a received squelch code, and to combine the plurality of communication signals according to the set of receive spatial processing weights to provide a combined signal, wherein the combined signal generated by the combiner is adapted to enhance the communication signal including the squelch code.
A machine-readable medium having stored thereon data representing instructions that, when executed by a processor of a two-way radio, cause the processor to perform operations comprising:
- receiving a plurality of versions of a communications signal by using a plurality of antenna elements, at least one version of the communications signal including a training signal;
- employing the training signal to determine a spatial processing strategy for combining at least a portion of the plurality of versions of the communications signal.
