摘要 |
Methods and devices for detecting a symbol in a radio channel and for cell identification are disclosed. A signal is received from the radio channel and the signal is filtered by a filter being responsive to the symbol thereby establishing a first signal. A second signal dependent on the noise floor of the received signal is established whereby a time interval expected to include multi-path components being excluded or suppressed. A third signal being the ratio between the first signal and the noise floor is established, and the presence of the symbol is detected by detecting a peak in the third signal. |
