Abstract
In the method of pulse shaping according to the present invention, a set of bits representing a symbol is received, and an output value is generated by adding or subtracting a received coefficient and a received value based on a first predetermined one of the set of bits. The generated output value is then supplied as either a real or imaginary output value based on at least a second predetermined one of the set of bits.
Claims22
A method of pulse shaping, comprising:
- a) receiving at least a first set of bits representing a first symbol;
- b) generating a value by one of adding and subtracting a received coefficient and a received value based on at least a first predetermined one of said first set of bits;
- and
- c) supplying said generated value as one of a real output value and an imaginary output value based on at least a second predetermined one of said first set of bits.
1 more element
A pulse shaper, comprising:
- an arithmetic block receiving at least a first predetermined one of a set of bits, a value and a coefficient, and performing one of addition and subtraction between said received value and said received coefficient based on said first predetermined bit in said set of bits;
- and
- a first selector selectively supplying output from said arithmetic block as one of a real output value and an imaginary output value based on at least a second predetermined one of said set of bits.
