    摘要： The present invention discloses a method for receiving and processing data. The method includes: convoluting a channel estimate value of a receive end with an SCH signal transmitted by a transmit end on an SCH and obtaining an SCH signal in a receive signal of the receive end; evaluating a difference between the receive signal and the SCH signal in the receive signal. An apparatus, and a user terminal are also disclosed in the present invention. By using the method and apparatus of the present invention, the SCH signal in a receiver may be restored and removed from the receive signal, and interference of the SCH on other channels may be eliminated, thereby improving performance of the receiver.

    摘要： Embodiments of the present invention provide a method and a system for removing a Radio Frequency (RF) Direct Current (DC) offset in a signal. The method includes: subtracting a canceling DC from a signal carrying an RF DC offset and generating an RF DC offset residual; outputting the signal when the RF DC offset residual in the signal is zero; adjusting the canceling DC according to the RF DC offset residual in the signal if the RF DC offset residual is not zero. The system includes a receiver, an RF DC offset canceling unit, a determining unit, a canceling DC adjusting unit, and an output unit. With embodiments of the present invention, the RF DC offset in the signal may be effectively removed.

    摘要： A method and device for estimating a Gaussian white noise power in a channel and a receiver are provided. The method includes performing a multi-path search on a received signal to find out paths of the signal; performing a noise estimation on one of the paths to acquire a total noise power of the path; performing an inter-path interference noise estimation on N paths spaced apart from the path by an integral number of chips to obtain an inter-path interference noise power of a single path of the signal, where N is an integer greater than or equal to 1; and subtracting the inter-path interference noise power from the total noise power to obtain the Gaussian white noise power. Through the technical solution of the disclosure, the Gaussian white noise power in a channel is obtained with a higher accuracy, so that the performance of equalization is enhanced.
