Advanced Testing of Wideband Terminals
نویسندگان
چکیده
Communication is migrating towards wideband transmission (50 Hz – 7 kHz). Terminals and networks are developed in order to provide a significant step towards higher speech quality. At the same time, standardization bodies like ETSI, GCF and the DECT Forum are working on new specifications for terminals. In order to setup appropriate speech quality measurements for wideband terminals, existing wideband test specifications were reviewed and analyzed. This contribution discusses current wideband standards and the development of new speech quality tests and requirements for mobile and fixed wideband terminals.

Optimum Frequency Response Characteristics for Wideband Terminals
In ETSI standard ES 202 739 and ES 202 740 a new testing technique for the measurement of wideband terminals is introduced. Tolerance masks are given for sending and receiving frequency response characteristics. As an important new concept in this standard no longer the ear reference point (ERP) but the free field reference point is used for determining the response characteristics in receiving...
متن کاملLCD-77-105 Secure Voice Telephone Systems: How the Department of Defense Can Save Millions (Unclassified Digest of a Classified Report)
In general, narrowband systems require more complex terminals which require more space and power and are more costly than wideband terminals. Conversely, in general, wideband systems require more costly transmission facilities. Most Defense tactical users require wideband facilities at the present time due to weight, size, and power constraints. Nontactical users generally are located in an ofk...
متن کاملA New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
متن کاملAccuracy of Relative Distance Measurement with Ultra Wideband System
Since very short pulse waves are transmitted, UWB systems have excellent accuracy in terms of distance measurement. In order to measure the distance between the terminals, the transmitted pulses have to be synchronized by a delay-lock-loop (DLL) in the receiver. In this paper the performance of the DLL is evaluated. Its performance depends the timing jitter between the local clocks of the termi...
متن کاملFrom Narrowband Telephony to Wideband Telephony
The restricted audio quality of today’s telephone networks is mainly due to the narrowband (NB) limitation to the frequency range from about 300 Hz to 3.4 kHz. Meanwhile, codecs for wideband (WB) telephony (50 Hz to 7 kHz) exist with significantly improved speech intelligibility and naturalness. However, the broad introduction of wideband speech coding will require strong efforts of both networ...
