Abstract
Data characterizing a first signal transmitted in an orthogonal frequency-division multiplexing (OFDM) system by a transmitter with one or more transmit antennas through an in-band channel and received by a receiver with a plurality of receive antennas can be received. The first signal can include one or more in-band pilot pulses. A channel quality for an out-of-band channel can be predicted based on the received data and a cross-correlation between an in-band channel and one or more out-of-band channels. Data characterizing the predicted channel quality for the out-of-band channel can be provided. Related apparatus, systems, techniques, and articles are also described.
Claims20
A method for implementation by one or more data processors forming part of at least one computing system, the method comprising:
- receiving, by at least one data processor, data characterizing a first signal transmitted in an orthogonal frequency-division multiplexing (OFDM) system by a transmitter with one or more transmit antennas through an in-band channel and received by a receiver with a plurality of receive antennas, the first signal comprising one or more in-band pilot pulses;
- predicting, using at least one data processor, a channel quality for an out-of-band channel based on the received data and a cross-correlation between an in-band channel and one or more out-of-band channels;
- and
- providing, using at least one data processor, data characterizing the predicted channel quality for the out-of-band channel.
A non-transitory computer program product storing instructions, which when executed by at least one data processor of at least one computing system, implement a method comprising:
- receiving, by at least one data processor, data characterizing a first signal transmitted in an orthogonal frequency-division multiplexing (OFDM) system by a transmitter with one or more transmit antennas through an in-band channel and received by a receiver with a plurality of receive antennas, the first signal comprising one or more in-band pilot pulses;
- predicting, using at least one data processor, a channel quality for an out-of-band channel based on the received data and a cross-correlation between an in-band channel and one or more out-of-band channels;
- and
- providing, using at least one data processor, data characterizing the predicted channel quality for the out-of-band channel.
A system comprising:
- at least one data processor;
- memory storing instructions which, when executed by the at least one data processor, causes the at least one data processor to perform operations comprising:
- receiving, by at least one data processor, data characterizing a first signal transmitted in an orthogonal frequency-division multiplexing (OFDM) system by a transmitter with one or more transmit antennas through an in-band channel and received by a receiver with a plurality of receive antennas, the first signal comprising one or more in-band pilot pulses;
- predicting, using at least one data processor, a channel quality for an out-of-band channel based on the received data and a cross-correlation between an in-band channel and one or more out-of-band channels;
- and
- providing, using at least one data processor, data characterizing the predicted channel quality for the out-of-band channel.
