Abstract:
1. A transmitter circuit configured to generate a Single-Carrier Discrete Cosine Transform (SC-DCT) OFDM signal for transmission, said transmitter circuit comprising: a signal processing chain configured to map K wherein said signal processing chain further includes one or more series DCT precoder stages between the serial-to-parallel converter and the prefix or padding circuit, each such stage configured to generate 2M output subcarriers from M input subcarriers, and to map the M input subcarriers to even-numbered or odd-numbered ones of the 2M output subcarriers, in dependence on a even/odd shift control signal applied to the stage, and each such stage comprising a DCT circuit followed by an IDCT circuit; and wherein a first one of the DCT precoder stages takes the K
