Patent abstract
Disclosed techniques for improving computational efficiency can be applied to synthesis and analysis in digital signal processing. A base discrete-time Orthogonal Frequency Division Multiplexing (OFDM) signal is generated by performing an inverse discrete Fourier transform (IDFT) on a set of data symbols. The set of data symbols is multiplied with a sparse update weight matrix to produce an update signal, and an IDFT is performed on the update signal to generate a discrete-time update signal. The discrete-time update signal is summed with the base discrete-time OFDM signal to produce an updated discrete-time OFDM signal.
