Data signals input to an adaptive overlapping transmitter are modulated by a plurality of overlapping chirps and transmitted over a wireless communication system to a non-coherent receiver. The coherent receiver includes a chirp matched filter which matches the chirps to an internal chirp signal, a delay filter which delays each chirp, a multiplier which multiplies each delayed chirp by a next chirp, an integrator which sums the amplitudes of the chirps and decision circuitry which determines the polarity of each sum and outputs a stream of ones and zeroes representing the data signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal detection method for non-coherent detection in a chirp spread spectrum communication system","description":"A system and methods for transmission and non-coherent detection of data signals modulated by a plurality of overlapping chirps in a chirp spread spectrum communication system (CSS).
