Spectral characterisation of the dicode PPM format [PDF]
, 2005 Dicode pulse position modulation (PPM) is a new modulation format that offers improved sensitivity over digital PPM but at a reduced line-rate. This Letter considers, for the first time, the spectral characterisation of the dicode PPM modulation format ...

Theory and assessment of an improved power spectral density estimator [PDF]
, 1990 This thesis is concerned with the processing of time domain signals received by a single sensor. An example of such signals is the radar return, which is used in one way or another to estimate the power spectral density a frequency representation of ...

A method to achieve spectral beam combining based on a novel symmetric grating
Frontiers in Physics, 2022 A symmetric grating is proposed to obtain higher output power in spectral beam combination by increasing the number of lasers and spectral utilization. The grating allows laser beams to be incident from both sides of the grating normal to achieve coaxial
