AFFINE FREQUENCY DIVISION MULTIPLEXING WAVEFORMS FOR DOUBLY DISPERSIVE CHANNELS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240094336 titled 'AFFINE FREQUENCY DIVISION MULTIPLEXING WAVEFORMS FOR DOUBLY DISPERSIVE CHANNELS
Simplified Explanation
The patent application describes a method of generating a signal by modulating multiple chirp signals with input symbols, where the chirp signals are characterized by a second-order bivariate polynomial. The coefficients of the quadratic terms of the polynomial are adjusted to achieve desired frequency diversity, and at least one coefficient can be modified based on channel state information to reduce effective Doppler spread in a discrete affine Fourier transform domain virtual channel.

Original Abstract Submitted
a signal may be generated by modulating a plurality of chirp signals with a set of input symbols. chirp signals may be characterized by a second order bivariate polynomial and the coefficients of the quadratic terms of the polynomial may be selected to achieve desired frequency diversity. furthermore, at least one of the coefficients may be adjusted based on channel state information to mitigate effective doppler spread in a discrete affine fourier transform domain virtual channel.
