Abstract
Disclosed are apparatuses for a communication device. An apparatus for a communication device includes control circuitry configured to use circular convolution for pulse shape filtering of a block of data symbols of a single carrier waveform to generate a block-wise single carrier (BWSC) symbol. The apparatus is also configured to insert one of a data-based cyclic prefix or a data-based cyclic postfix into the BWSC symbol one of before the pulse shape filtering or after the pulse shape filtering. An apparatus for a communication device includes control circuitry configured to remove one or more of a cyclic prefix or a cyclic postfix from a received BWSC symbol, and use circular convolution to demodulate the received BWSC symbol.
Claims23
An apparatus for a communication device, comprising:
- control circuitry configured to:
- use circular convolution for pulse shape filtering of a block of data symbols of a single carrier waveform to generate a block-wise single carrier (BWSC) symbol, using the circular convolution including filtering the block data symbols with a pulse shape filter initialized to an initial state to generate a filtered block of data symbols;
- insert one of a data-based cyclic prefix or a data-based cyclic postfix into the BWSC symbol one of before the pulse shape filtering or after the pulse shape filtering;
- and
- window and overlap the BWSC symbol with one or more other BWSC symbols to smooth a transition between the BWSC symbol and the one or more other BWSC symbols.
An apparatus for a communication device, comprising:
- control circuitry including one or more processors;
- one or more non-transitory computer-readable storage media operably coupled to the one or more processors and including computer-readable instructions stored thereon, the computer-readable instructions configured to instruct the one or more processors to:
- remove one or more of a cyclic prefix or a cyclic postfix from a received block-wise single carrier (BWSC) symbol;
- add a periodic extension comprising a prefix periodic extension, a postfix periodic extension, or a combination thereof to the BWSC symbol to generate an extended BWSC symbol;
- filter the extended BWSC symbol to produce a filtered BWSC symbol;
- downsample the filtered BWSC symbol to obtain a block of periodically extended symbols;
- and
- remove redundancies from the block of periodically extended symbols to obtain a block of data symbols.
An apparatus for a communication device, comprising:
- control circuitry configured to:
- remove at least one of a cyclic prefix or a cyclic postfix from a received block-wise single carrier (BWSC) symbol;
- and
- filter the received BWSC symbol with a match filter initialized to an initial state to circularly convolve the BWSC symbol to generate a filtered BWSC symbol, the match filter matching a filter used by a far-end communication device to generate the received BWSC symbol.
