Abstract
Embodiments herein disclose a method and system for designing a waveform for data communication. The method includes applying, by a phase rotation applying unit, a constellation specific phase rotation between consecutive data symbols in a data stream to obtain a constellation rotated data stream. Further, the method includes introducing, by a frequency domain pulse shaping filter, an inter symbol interference (ISI) between modulated data symbols of the constellation rotated data stream, such that the ISI develops the waveform of the constellated rotated data stream to be transmitted.

A method for designing a waveform for data communication, the method comprising:
- applying, by a phase rotator, a constellation specific phase rotation between consecutive data symbols in a data stream to obtain a constellation rotated data stream;
- obtaining, by a repeater, a spread signal from the constellation rotated data stream in a frequency domain;
- and
- applying, by a controller, a frequency domain pulse shaping filter to the spread signal, wherein the frequency domain pulse shaping filter is obtained using a Discrete Fourier transform (DFT) of a sampled linearized Gaussian pulse.
A transmitter for designing a waveform for data communication, the transmitter comprising:
- a phase rotator configured to apply a constellation specific phase rotation between consecutive data symbols in a data stream to obtain a constellation rotated data stream;
- and
- a repeater configured to obtain a spread signal from the constellation rotated data stream in a frequency domain;
- a controller configured to apply a frequency domain pulse shaping filter configured to the spread signal, wherein the frequency domain pulse shaping filter is obtained using a Discrete Fourier transform (DFT) of a sampled linearized Gaussian pulse.
