The combined weight of the apparatus and method of obtaining

The present invention provides a method and apparatus for obtaining combined weights, wherein the method comprises; selecting a channel for calculating a channel estimate of a time period; calculating a channel estimate in the time period of the channel; the channel estimation interpolation operation, and based on the channel obtained after interpolation combining weights to obtain the receiver estimates weight. With the above technical solution provided by the invention, to solve the related art, the combined weight updating slow, can not accurately reflect the technical problems channel variation letters, improving the weight updating speed combining weights, and the combined weight of the particle size present is smaller, so as to achieve resistant to the fast varying fading channel with some degree of residual frequency offset, the receiver bit error rate is reduced.
