Efficient Data Transmission Using Multiple-Valued Pulse-Position Modulation

This paper proposes multiple-valued pulse position modulation (MVPPM) techniques to achieve highly efficient data transmission in VLSI systems. The MVPPM coding employs 2-dimensional information representation in both time and amplitude domain to increase data rates. This time-domain information processing uses timing resolution, and therefore fits well with advanced high-speed low-voltage CMOS processes. An MVPPM transceiver is designed and simulated using SPICE to demonstrate the capability of compensating for deterioration of signals caused by interconnections.
