Abstract
An apparatus and method for inserting a cyclic postfix for a time-rotated symbol in a communication system. In one embodiment, the apparatus includes a time pre-rotation module configured to time shift bits of at least one of ending samples of a symbol to a beginning of the symbol to form a time-rotated symbol. The apparatus also includes an interpolator configured to construct an up-sampled symbol from the time-rotated symbol and a cyclic postfix module configured to insert a cyclic postfix at an end of the up-sampled symbol to form an expanded up-sampled symbol.
Claims20
An apparatus, comprising:
- time pre-rotation module configured to time shift bits of at least one of ending samples of a symbol to a beginning of said symbol to form a time-rotated symbol;
- an interpolator configured to construct an up-sampled symbol from said time-rotated symbol;
- and
- a cyclic postfix module configured to insert a cyclic postfix at an end of said up-sampled symbol to form an expanded up-sampled symbol.
An apparatus, comprising:
- means for time shifting bits of at least one of ending samples of a symbol to a beginning of said symbol to form a time-rotated symbol;
- means for constructing an up-sampled symbol from said time-rotated symbol;
- and
- means for inserting a cyclic postfix at an end of said up-sampled symbol to form an expanded up-sampled symbol.
A computer program product comprising a program code stored in a computer readable medium configured to shift bits of at least one of ending samples of a symbol to a beginning of said symbol to form a time-rotated symbol, construct an up-sampled symbol from said time-rotated symbol, and insert a cyclic postfix at an end of said up-sampled symbol to form an expanded up-sampled symbol.
A method, comprising:
- time shifting bits of at least one of ending samples of a symbol to a beginning of said symbol to form a time-rotated symbol;
- constructing an up-sampled symbol from said time-rotated symbol;
- and
- inserting a cyclic postfix at an end of said up-sampled symbol to form an expanded up-sampled symbol.
