Abstract
A method including receiving a data subframe having a plurality of symbols, determining a location of invalid pseudo time-domain samples in the data subframe, and discarding invalid pseudo time domain samples and recovering valid pseudo time domain samples to produce an updated data subframe, and processing the updated data subframe to produce demodulated data.
Claims20
A method, comprising:
- receiving a data subframe having a plurality of symbols;
- determining a location of invalid pseudo time-domain samples in the data subframe;
- and
- discarding invalid pseudo time domain samples and recovering valid pseudo time domain samples to produce an updated data subframe;
- and
- processing the updated data subframe to produce demodulated data.

A demodulator apparatus, comprising:
- an automatic gain controller, AGC, to scale a received signal having a plurality of subframes;
- a fast Fourier transform, FFT, to transform the received signal into the frequency domain;
- a physical Sidelink channel to decode the frequency domain signal, the physical Sidelink channel including an inverse discrete Fourier transform, IDFT to transform a data subframe to the time domain and a symbol controller configured to determine a location of invalid pseudo time-domain samples in the subframe and output an updated data subframe, wherein the physical Sidelink channel further processes the updated data subframe to produce demodulated data.
A method, comprising:
- receiving a data subframe having a plurality of symbols;
- determining, by way of a symbol controller, a location of invalid pseudo time-domain samples in the data subframe;
- discarding, by way of the symbol controller, invalid pseudo time domain samples and recovering valid pseudo time domain samples to produce an updated data subframe;
- and
- processing the updated data subframe to produce demodulated data.
