Methods, systems, and articles of manufacture for joint decoding of packets in wireless networks using chirp spread-spectrum modulation

A method of providing wireless communications in a wireless network, the method comprising:

• wirelessly receiving a chirp spread-spectrum modulated signal at a first gateway device, the chirp spread-spectrum modulated signal being transmitted by a remote client device;
• demodulating the chirp spread-spectrum modulated signal at the first gateway device to provide demodulated data at the first gateway device;
• processing the demodulated data to provide an indication that a decode of a packet including the demodulated data failed;
• filtering time adjacent chirps included in the demodulated data with time adjacent chirps of a known preamble included in a chirp spread-spectrum modulated signal to provide filtered data at the first gateway device;
• and
• transmitting a message from the first gateway device to a remote server responsive to an amplitude of the filtered data exceeding a threshold value and the indication that the decode of the packet including the demodulated data failed.
