Abstract: The present invention discloses a signal communication method having re-sampling mechanism that includes steps outlined below. Sampled data of a data signal is obtained. A time difference between an actual sampling time point and an ideal sampling time point is calculated. A closet time point closest to the ideal sampling time point within a sampling time interval is selected. Operation sampled data within a predetermined range around the target sampled data is selected from the sampled data. A group of response terms are retrieved from a pre-stored lookup table according to the closest time point to substitute the response terms and the time difference into a parameter calculation equation to generate a group of re-sampling response parameters. A calculation is performed based on the operation sampled data and the re-sampling response parameters to generate a re-sampled value of the target sampled data.

Abstract: A cooperative precoding method, applied in a communication system comprising a coordinating device and multiple serving stations, is provided. The cooperative precoding method includes the following steps: the coordinating device obtaining multiple carrier frequency offset (CFO) parameters of the serving stations with respect to a user device; generating multiple cooperative encoded sequences; assigning the cooperative encoded sequences to the serving stations, respectively, according to an order of the plurality of CFO parameters; and the plurality of serving stations transmitting the cooperative encoded sequences, respectively, to the user device. Each cooperative encoded sequence is transmitted over multiple subcarriers.
