Reduced latency look-ahead for signal detector

A computer program product including one or more non-transitory machine-readable mediums encoded with instructions that when executed by one or more processors cause a process to be carried out for signal detection, the process comprising:

• down converting a digitized signal to a first baseband signal at a first decimation rate such that the first baseband signal is provided at a first latency with a first signal to noise ratio (SNR), the first latency and the first SNR based on the first decimation rate;
• down converting the digitized signal to a second baseband signal at a second decimation rate such that the second baseband signal is provided at a second latency with a second SNR, the second latency and the second SNR based on the second decimation rate, wherein the second decimation rate is greater than the first decimation rate, the second latency is greater than the first latency, and the second SNR is greater than the first SNR;
• and
• generating a detection threshold based on the first baseband signal, the detection threshold generated prior to completion of the generation of the second baseband signal.

A method for signal detection, the method comprising:

• down converting, by a processor-based system, a digitized signal to a first baseband signal at a first decimation rate such that the first baseband signal is provided at a first latency with a first signal to noise ratio (SNR), the first latency and the first SNR based on the first decimation rate;
• down converting, by the-processor based system, the digitized signal to a second baseband signal at a second decimation rate such that the second baseband signal is provided at a second latency with a second SNR, the second latency and the second SNR based on the second decimation rate, wherein the second decimation rate is greater than the first decimation rate, the second latency is greater than the first latency, and the second SNR is greater than the first SNR;
• and
• generating, by the processor-based system, a detection threshold based on the first baseband signal, the detection threshold generated prior to completion of the generation of the second baseband signal.
