Amplitude modulation of a pulse carrier. Abbreviated PAM.

pulse-amplitude modulation

A technique in which a signal is broken down into bits, and the amplitude of each of these bits is measured to give a series of discrete values. See pulse modulation.

An alternative to PSK that is claimed to be a simpler solution is four-level pulse-amplitude modulation (PAM-4).
This, coupled with transceivers using wavelength division multiplexing and/or pulse-amplitude modulation technology, provides a path for CommScope customers to grow their fiber throughput capacity from 10G to 100G and beyond with maximum fiber reach and minimum fiber count, enabling them to cost-effectively keep pace with the bandwidth explosion.
Altera is demonstrating today the FPGA industry's first dual-mode 56-Gbps pulse-amplitude modulation with 4-levels (PAM-4) and 30-Gbps non-return-to-zero (NRZ) transceivers.
Knowing of a problem beforehand might give you an opportunity to design it right the first time, perhaps using a wider line, a shorter length, a lower dissipation factor laminate, routing on a surface microstrip or a silicon processing technique such as pre-emphasis, equalization or pulse-amplitude modulation (PAM).
Common digital modulations include pulse-amplitude modulation (PAM), frequency-shift keyed (FSK), binary-phase-shift keyed (BPSK), and quadrature-phase-shift keyed (QPSK).
