Abstract
Embodiments of the present disclosure disclose method and
transmitter to generate and transmit a waveform with an
optimized peak to average power ( PAPR ) in a communica
tion network . The method comprises performing a constel
lation rotation on input data symbols to create a rotated data
symbols , wherein the input data symbols is obtained by
performing at least one of prefixing a modulation data with
first predefined number ( N1 ) of zero ' s and post - fixing the
modulation data with second predefined number ( N2 ) of
zero ' s . Also , the method comprises performing convolution
operation on the input data symbols using one or more filter
coefficients to produce a symbol level filtered data . Further , the method comprises pulse shaping the symbol level fil
tered data to generate a pulse shaped data sequence and
processing the pulse shaped data sequence to generate a
waveform .
