forward error signal
1Forward error correction — In telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding[1] is a technique used for controlling errors in data transmission over unreliable or noisy communication channels. The central idea is… …
2Forward Error Correction — Vorwärtsfehlerkorrektur (kurz FEC von engl. forward error correction, manchmal auch EDAC, für engl. error detection and correction) ist eine Technik, die dazu dient, die Fehlerrate bei der Speicherung oder der Übertragung digitaler Daten zu… …
3Error detection and correction — In mathematics, computer science, telecommunication, and information theory, error detection and correction has great practical importance in maintaining data (information) integrity across noisy channels and less than reliable storage… …
4Reed–Solomon error correction — Reed Solomon error correction is an error correcting code that works by oversampling a polynomial constructed from the data. The polynomial is evaluated at several points, and these values are sent or recorded. Sampling the polynomial more often… …
5Soft error — In electronics and computing, an error is a signal or datum which is wrong. Errors may be caused by a defect, usually understood either to be a mistake in design or construction, or a broken component. A soft error is also a signal or datum which …
6Quantization (signal processing) — In digital signal processing, quantization is the process of approximating a continuous range of values (or a very large set of possible discrete values) by a relatively small set of discrete symbols or integer values.More specifically, a signal… …

9GPS signals — Global Positioning System (GPS) satellites broadcast radio signals to enable GPS receivers to determine location and synchronized time. Anatomy of a GPS signal GPS signals include ranging signals, used to measure the distance to the satellite,… …
10Spectral efficiency — Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is… …
