| OAM&P |
Operations, Administration, Maintenance & Provisioning Center |
An operations center used to operate, administer, maintain and provision the network. |
| OCQPSK |
Orthogonal Complex Quadrature Phase Shift Keying |
|
| OFDM |
Orthogonal Frequency Division Multiplex |
|
| OMC |
Operations & Maintenance Center |
A location used to operate and maintain a wireless network. |
| OQPSK |
Offset Quadrature Phase Shift Keying |
A type of QPSK modulation that offsets the bit streams on the I and Q channels by a half bit. This reduces amplitude fluctuations and helps improve spectral efficiency. |
| ORFS |
Output Radio Frequency Spectrum |
A measurement for GSM signals that tests for interference
in the adjacent frequency channels (ARFCNs) and results from two effects:
modulation within the bursts and the power that ramps up and down, or switching
transients. ORFS is a critical GSM transmitter measurement. |
