Abstract
A system for signal processing is provided. A sampling delay system generates a plurality of sampling delay values. A plurality of programmable delays each receives one of the sample delay values. A plurality of sample and hold units, each coupled to one of the programmable delays, generates a sample of a received signal in response to an input from the programmable delay.
Claims19
A system for signal processing comprising:
- a sampling delay system to generate one or more sampling delay values;
- a channel selector to receive channel selection data and generate one or more of the sampling delay values;
- a plurality of programmable delays, each to receive one of the sampling delay values;
- and
- a plurality of sample and hold units, each coupled to one of the programmable delays, to generate a sample of a received signal in response to an input from the programmable delay.
2 more elements
A method for processing a signal, comprising:
- receiving the signal at each of a plurality of sample and hold units;
- sampling the signal at each of the sample and hold units in response to a signal from a programmable delay;
- summing the sampled signals to generate an output signal;
- determining whether a location of a transmitter has changed relative to a position of an antenna;
- and
- determining a new delay value for the programmable delay if the location of the transmitter has changed.
3 more elements
A system for signal processing comprising;
- a sampling delay system to generate a plurality of sampling delay values;
- a channel direction finder to determine a location of a communication channel and provide location data to the sampling delay system, wherein the sampling delay system can generate the plurality of sampling delay values based on the location data;
- a plurality of programmable delays, each to receive one of the sampling delay values:
- and
- a plurality of sample and hold units, each coupled to one of the programmable delays, to generate a sample of a received signal in response to an input from the programmable delay.
