A time-frequency representation which uses a signal-dependent, radially Gaussian kernel that adapts over time. The code provides an excellent ambiguity domain filter for time-frequency analysis.
Just run the script main_AOK.m to see it in action. The test signal includes three impulses, two simultaneous sinusoids, a Gaussian pulse, and two parallel linear chirps.
The algorithms are described in detail in the paper:
"An Adaptive Optimal-Kernel Time-Frequency Representation" by D. L. Jones and R. G. Baraniuk, IEEE Transactions on Signal Processing, Vol. 43, No. 10, pp. 2361--2371, October 1995.
Special thanks to Richard Baraniuk for making the original C code available.
