On the Optimality of Uniform Pulse Amplitude Modulation

IEEE Transactions on Information Theory, 2006
We characterize the optimal M-ary pulse amplitude modulation (PAM) constellation under a general energy constraint. It is shown that uniform M-ary PAM may not always yield the best signal design, e.g., under the average energy constraint.

Optimal Amplitude Design for MN-Ary Pulse Position Amplitude Modulation

2012 IEEE Vehicular Technology Conference (VTC Fall), 2012
The MN-ary pulse position amplitude modulation (PPAM) signal is constructed by combining M-ary pulse amplitude modulation and N-ary pulse position modulation. The PPAM scheme provides improved reciprocity in system performance and computational complexity. In this paper, we investigate the Euclidean distance in a set of MN-ary PPAM signals.

Amplitude-modulated composite pulses

Journal of Magnetic Resonance (1969), 1988
One of the most important developments in the field of magnetic resonance in the past decade has been the introduction of composite pulse sequences (I). These may be either several pulses of specified length and phase applied sequentially or a single complex pulse of continuously varying phase and/or amplitude which compensate for the imperfections ...

Margin Measurements of Pulse Amplitude Modulation Channels

Optical Data Storage Topical Meeting, 1991
High capacity optical disk drives are in production which conform to the ANSI proposal BSR X 3.191, known as the 130mm Write-Once Sampled Servo RZ Selectable Pitch Optical Disk Cartridge (reference 1). The capacity of these cartridges is 1280 million bytes available to the user, under ECC protection.
