Abstract
The present disclosure describes systems, apparatuses, methods, and computer-readable media for multi-channel software-defined radio (SDR) audio transceivers, multi-user audio systems using the same, and methods of using the same. SDR audio transceivers can comprise an antenna and/or radio transmitter. SDR audio transceivers can be configured for multi-channel audio transmission. The multi-channel audio transmission can include wideband channels or channels allocated across a wideband of spectrum. The multi-channel audio transmission can include narrowband channels or channels allocated to a relatively narrower band of spectrum.
Claims20
An audio system comprising:
- one or more wireless audio transmitters configured to transmit audio data;
- and
- one or more antennas configured to receive the audio data transmitted by the one or more wireless audio transmitters;
- and
- a multi-channel receiver (MCR) configured to receive the audio data from the one or more antennas, the MCR comprising:
- a processor configured to operate one or more software defined radio functions;
- a memory in operable communication with the processor, the memory storing program code;
- and
- a field programmable gate array (FPGA) in operable communication with the processor,
- wherein the memory and the program code are configured, with the processor, to cause the MCR to at least:
- cause at least a portion of the IC-FPGA to scan for available spectrum using at least one of the one or more antennas;
- determine one or more of:
- an antenna configuration, a transmission mode, an audio channel allocation, or a number of audio channels to be accommodated by the MCR to improve use of the available spectrum;
- and
- provide configurational information, using the processor, to the FPGA such that the FPGA can cause configuration or reconfiguration of:
- at least one of the antennas based on the antenna configuration, the transmission mode, or the number of audio channels to be accommodated by the MCR.
An audio system comprising:
- a multi-channel receiver (MCR) configured to receive audio data, the MCR comprising a field-programmable gate array (FPGA) and one or more antenna, the MCR being configured at least to:
- determine or define a plurality of audio channels for receiving audio;
- configure the one or more antennas to receive audio in at least a portion of the plurality of audio channels;
- scan, using at least a portion of the FPGA, for available spectrum;
- determine, based at least on the available spectrum, configurational information for the MCR, wherein the configurational information comprises one or more of:
- antenna modes, transmission modes, or a number of audio channels to be accommodated by the MCR to improve use of the available spectrum;
- and
- configure, based on the configurational information and using the FPGA, the one or more antennas.
A method comprising:
- scanning, by a multi-channel receiver (MCR), for available spectrum using at least a portion of a field-programmable gate array (FPGA) of the MCR and at least one of one or more antennas;
- determining one or more of:
- an antenna configuration, a transmission mode, an audio channel allocation, or a number of audio channels to be accommodated by the MCR to improve use of the available spectrum;
- and
- providing configurational information to the FPGA such that the FPGA can cause configuration or reconfiguration of:
- at least one of the antennas based on the antenna configuration, the transmission mode, or the number of audio channels to be accommodated by the MCR.
