Abstract: The present invention relates to a receiving node, and to a related method of adjusting a frequency domain channel estimate in a receiving node of a wireless communication system using Orthogonal Frequency Division Multiplexing. The method comprises estimating (210) a phase rotation of the frequency domain channel estimate, and compensating (220) for the estimated phase rotation in the frequency domain channel estimate. It also comprises transforming (230) the compensated frequency domain channel estimate into a time domain channel estimate, filtering (240) the time domain channel estimate to suppress noise, transforming (250) the filtered time domain channel estimate back into a noise suppressed frequency domain channel estimate, and adding (260) the estimated phase rotation in the noise suppressed frequency domain channel estimate to achieve an adjusted and improved frequency domain channel estimate.

Abstract: A noisy frequency-domain channel estimate enhancer includes an over-sampler configured to transform the noisy frequency-domain channel estimate into a time-domain channel estimate that is virtually over-sampled by an integer factor m. The over-sampler is connected to a de-interleaver configured to divide the time-domain channel estimate into m de-interleaved sub-vectors. The de-interleaver is connected to a suppressor configured to suppress noisy taps from each de-interleaved sub-vectors to form m noise suppressed sub-vectors. The suppressor is connected to a selector configured to select a noise suppressed sub-vector associated with a highest signal-to-noise ratio. The selector is connected to a discrete Fourier transformer configured to transform the selected noise suppressed sub-vector into a noise suppressed preliminary frequency-domain channel estimate. The discrete Fourier transformer is connected to a phase-shifter configured to phase-adjust the taps of the noise suppressed preliminary frequency-domain channel estimate to form an enhanced frequency-domain channel estimate.

Abstract: A method for random access of Machine to Machine (M2M) terminals is applied to a plurality of M2M terminals. The method includes dividing the plurality of M2M terminals into at least one terminal group, and allocating an identifier for each terminal group. After receiving the paging broadcast signaling transmitted by the base station, an M2M terminal in a terminal group determines whether the terminal group identifier carried in the paging broadcast signaling is the identifier of the terminal group that includes the M2M terminal. If true, the M2M terminal starts a random access process. A base station transmits a paging broadcast signaling on the basis of a terminal group rather than issuing a paging broadcast signaling only to individual M2M terminals so that a plurality of M2M terminals can be randomly accessed smoothly and efficiently without causing network access congestion nor affecting the use of public network users.
