At least one embodiment of a correlator comprising a plurality of correlator taps is configurable to provide synchronization and symbol modulation for a plurality of modulation systems. Among other uses, at least one embodiment of the correlator can provide a coarse symbol timing value. In response to determining the coarse symbol timing value, a receiver can receive a signal. Among other uses, at least one embodiment of the correlator can provide a carrier frequency offset (CFO) estimate. In response to determining the CFO estimate, a receiver can receive a signal.

Configurable correlator for joint timing and frequency synchronization and demodulation

An imaging system and method that captures compressive sensing (CS) measurements of a received light stream, and also obtains samples of background light level (BGLL). The BGLL samples may be used to compensate the CS measurements for variations in the BGLL. The system includes: a light modulator to spatially modulate the received light stream with spatial patterns, and a lens to concentrate the modulated light stream onto a light detector. The samples of BGLL may be obtained in various ways: (a) injecting calibration patterns among the spatial patterns; (b) measuring complementary light reflected by digital micromirrors onto a secondary output path; (c) separating and measuring a portion of light from the optical input path; (d) low-pass filtering the CS measurements; and (e) employing a light power meter with its own separate input path. Also, the CS measurements may be high-pass filtered to attenuate background light variation.
