Abstract
The present application provides a non-orthogonal demodulation module, receiving a received signal and the received signal is related to a summation of a plurality of transmitted signals. The plurality of transmitted signals are corresponding to a plurality of frequencies, and the plurality of transmitted signals are not orthogonal to each other. The non-orthogonal demodulation module comprises a mixing-and-integrating unit, configured to perform mixing operations and integrating operations on the received signal respectively at the plurality of frequencies, to generate a plurality of in-phase components and a plurality of quadrature components corresponding to the plurality of frequencies; and a decoding unit, configured to generate at least a decoding matrix, and compute a plurality of energies corresponding to the plurality of transmitted signals according to the at least a decoding matrix, the plurality of in-phase components and the plurality of quadrature components.
