The present invention provides a terminal supporting eNFC and its processing method, in which a card emulation mode is disabled when a user card does not support SWP, and NFC in non card emulation modes can further be supported. A mobile terminal disabling/enabling the NFC function is implemented by the interaction of the mobile terminal with a NFC emulation front end chip therein. When the terminal determines that the user card does not support the SWP interface, it disables the NFC function. If the terminal is required to work in a non card emulation mode, the terminal starts a NFC application in the non card emulation, mode, and enables the NFC function when determining that the NFC function is in a disabled state; after the NFC ends, the terminal disables the NFC function when determining that the user card does not support the SWP interface.

Quick frequency tracking (QFT), quick time tracking (QTT), and non-causal pilot filtering (NCP) are used to detect sporadically transmitted signaling, e.g., paging indicators. For QFT, multiple hypothesized frequency errors are applied to an input signal to obtain multiple rotated signals. The energies of the rotated signals are computed. The hypothesized frequency error with the largest energy is provided as a frequency error estimate. For QTT, coherent accumulation is performed on the input signal for a first set of time offsets, e.g., early, on-time, and late. Interpolation, energy computation, and non-coherent accumulation are then performed to obtain a timing error estimate with higher time resolution. For NCP, pilot symbols are filtered with a non-causal filter to obtain pilot estimates for one antenna for non-STTD and for two antennas for STTD. The frequency and timing error estimates and the pilot estimates are used to detect the signaling.
