DFTS-OFDM using sampling rate conversion

Methods and devices are provided in which the DFT-SODFM signal is generated through Px upsampling of QAM symbols s[m], frequency offsetting the up sampled QAM symbols, digital filtering with circular convolution with rotated filter coefficients and Qx down sampling. Variants are possible exploiting...

More Information
Summary:Methods and devices are provided in which the DFT-SODFM signal is generated through Px upsampling of QAM symbols s[m], frequency offsetting the up sampled QAM symbols, digital filtering with circular convolution with rotated filter coefficients and Qx down sampling. Variants are possible exploiting linear convolution.
