occupied bandwidth

occupied bandwidth

[′äk·yə‚pīd ′band‚width]
(communications)
Frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers radiated are each equal to 0.5% of the total mean power radiated by a given emission.

For R&D and test engineers in lab environments, the MS2760A can measure channel power, adjacent channel power, spurious emissions, and occupied bandwidth. The MS2760A allows measurements to be taken directly at the DUT, unlike bench-top models that require expensive cables that can add loss.
However, when the MUSIC method is applied to FM reception, restrictions in factors including the number of array antenna elements and the occupied bandwidth result in issues of separation performance in relation to multipath waves in urban environments.
Therefore, the chip rate needed and the occupied bandwidth required will be independent of the number of aircraft in the network.
Additional features include automatic measurements of Channel Power (CP), Adjacent Channel Power Ratio (ACPR) and Occupied Bandwidth (OBW), and waveform demodulation.
Moreover, in multicast scheme, whenever the last viewer of a certain TV channel group leaves the system, the base station immediately stops multicasting this TV channel program and releases the occupied bandwidth resources.
Each analyzer has dedicated routines for simple one-button measurements of field strength, channel power, occupied bandwidth, adjacent channel power ratio (ACPR), carrier-to-interference ratio (C/I), and AM/FM/SSB demodulator.
In this paper, the DOA estimation algorithm using a time-frequency conversion pre-processing method with a signal OBW (Occupied Bandwidth) analysis was proposed and the effectiveness was verified through the simulation.
The rules and guidelines address the amount of power output and the occupied bandwidth that can be applied in the allocated free spectrum.
It automates measurements such as error vector magnitude, frequency, power, occupied bandwidth and packet error rate on signals generated by a WirelessHD device under test conditions.
In FM, with an increasing modulation index, the total power in the modulated signal remains constant while the occupied bandwidth increases.
Most common measurements, including channel power, adjacent-channel-power ratio (ACPR), and occupied bandwidth (OBW), can be made with a single key.
The automated tests include occupied bandwidth, spectrum mask tests and on/off ratio.
