A theoretical model for time code modulation
The traditional waveform coding techniques for digital communication systems convert the original analog input signal into a digital bit stream using uniform sampling in the time domain, i.e., PCM, DM, ADPCM. In this paper we propose the Time Code Modulation (TCM) technique as an alternative coding scheme, where information is extracted from the signal, only at the time instants when necessary....
متن کاملA Strategy for Generating Time-Predictable Code
Prohibiting external control is one of the key principles engineers apply when building time-predictable computer systems (e.g., time-triggered computer systems do not react to any external interrupts from sensors or devices, but all actions of these computer systems are triggered solely by the progression of the local clock). In this paper we apply this principle of prohibiting external contro...
متن کاملA Non-MDS Erasure Code Scheme for Storage Applications
This paper investigates the use of redundancy and self repairing against node failures indistributed storage systems using a novel non-MDS erasure code. In replication method, accessto one replication node is adequate to reconstruct a lost node, while in MDS erasure codedsystems which are optimal in terms of redundancy-reliability tradeoff, a single node failure isrepaired after recovering the ...
متن کاملEcho time optimization for linear combination myelin imaging.
A 3-echo linear combination myelin imaging method is presented. The echo times and weights are chosen such that the signal-to-noise ratio (SNR) of myelin-water is maximized, and signals from other white matter components are sufficiently suppressed. Interfering tissue water and cerebrospinal fluid (CSF) signals are much stronger than myelin due to their longer T2 and abundance. By carefully opt...
