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 communication network. The method comprises performing a constellation rotation on input d¡ta symbols to create a rotated d¡ta symbols, wherein the input d¡ta symbols is obtained by performing at least one of prefixing a modulation d¡ta with frst predefned number (Nl) of zero's and post-fxing the modulation d¡ta with second predefined number (N2) of zero's. Also, the method comprises performing convolution operation on the input d¡ta symbols using one or more filter coeffcients to produce a symbol level fltered d¡ta. Further, the method comprises pulse shaping the symbol level fltered d¡ta to generate a pulse shaped d¡ta sequence and processing the pulse shaped d¡ta sequence to generate a waveform. FIGS. 3A-3D
