Abstract: A modulation scheme for long range transceiver utilizing a processing scheme in combination with a Hadamard transform is disclosed. The processing scheme can correspond to an industry standard or to other processing schemes. An input signal is parallelized through serial to parallel conversion. The processed parallel signals are orthogonalized using a Hadamard transform to allow multiple channel signals with increased throughput. Accordingly, the long range modulation scheme of this invention can achieve high efficiency and increased throughput while meeting performance goals of long range signal transmission.
