Bus reversable orthogonal differential vector signaling codes

Mohammad Amin Shokrollahi

Properties and the construction method of Orthogonal Differential Vector Signaling Codes are disclosed which are tolerant of order-reversal, as may occur when physical routing of communications channel wires causes the bus signal order to be reversed. Oper ...

Methods and systems for low-power and pin-efficient communications with superposition signaling codes

Mohammad Amin Shokrollahi, Harm Cronie

Abstract A communication system uses a bus to transmit information, by receiving signals and mapping them to a second set of signals representing codewords of a superposition signaling code, and transmitting the second set of signals. The superposition sig ...

Vector signaling codes with high pin-efficiency for chip-to-chip communication and storage

Mohammad Amin Shokrollahi

An alternative type of vector signaling codes having increased pin-efficiency normal vector signaling codes is described. Receivers for these Permutation Modulation codes of Type II use comparators requiring at most one fixed reference voltage. The resulti ...

Vector signaling with reduced receiver complexity

Mohammad Amin Shokrollahi

Methods and apparatuses are described to determine subsets of vector signaling codes capable of detection by smaller sets of comparators than required to detect the full code. The resulting lower receiver complexity allows systems utilizing such subset cod ...

A Versatile Spectrum Shaping Scheme for Communicating Beyond Notches in Multi-Drop Interfaces”

Mohammad Amin Shokrollahi, Seyed Armin Tajalli, Christoph Walter, Ali Hormati, Kiarash Gharibdoust

This paper proposes a signal shaping technique to increase the data rate of high-speed SerDes communication systems over multi-drop bus interfaces. This scenario creates a channel with deep notches in its spectrum, and therefore the effective data rate in ...

ISI Tolerant Signaling: A Comparative Study of PAM4 and ENRZ

Mohammad Amin Shokrollahi, Ali Hormati

A thorough analysis has been carried out to study and compare the sensitivity of two signaling methods (PAM4 and ENRZ) to inter-symbol interference (ISI). While both signaling methods are considered to be major candidates for implementing 56+ Gbps serial c ...
