Methods and apparatuses for providing a stable wideband noise signal |
摘要 |
Methods and apparatuses for determining uplink receive signal path characteristics in a wireless communication system are disclosed. In one embodiment, a tower-top noise source (TTNS) is provided such that it is permanently affixed in close proximity to a receive antenna. The TTNS preferably has an output that includes a wideband noise signal having predetermined characteristics. The TTNS output is selectively connected to a receive signal path that includes a tower-top low-noise amplifier (TTLNA). An altered version of the wideband noise signal is received at the output of the receive signal path, and a characteristic of the altered wideband noise signal is measured. |
