Abstract
Devices and methods for enhancing forward error correction techniques for communications using chirp spread spectrum are disclosed. Systems, devices, and methods for error correction coding and decoding are described. On the coding side, K bits of data are sequentially loaded into an M bit by N bit (M×N) matrix in a first direction as Q sequences of D bits, each D bit row of data in the M×N matrix is coded with an error correction code to generate an M bit row of coded data, each Q bit column in the M×N matrix is coded with the error correction code to generate N bits of coded data, N sequences of M bits are sequentially unloaded from the M×N matrix in a second direction, and a chirp signal is generated having a plurality of chirps.
