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 plurality of signal processing chains, wherein each signal processing chain configured to map K wherein said signal processing chain further includes one or more DCT precoder stages between the serial-to-parallel converter and the prefix or padding circuit, each such stage i, where i=1, 2, . . . , S, configured to generate 2M wherein a first one of the DCT precoder stages takes the K wherein each of the plurality of said signal processing chains is associated with different series of information symbols to be transmitted and a shift control circuit that is configured to generate even/odd shift control signals for each said signal processing chain, such that orthogonal patterns of even or odd subcarrier mapping are used between the different signal processing chains.
