Abstract: This invention presents a synchronization method for uplink, and is based on UE JT technology. During downlink, UE sets up the downlink synchronization; UE undertakes the downlink channel estimation; UE, according to the estimated downlink channel estimation result, constructs transport matrix A, and the uplink synchronization code matrix d to be transmitted by UE. Then UE obtains the uplink pilot frequency transmission data s, which includes the latest downlink channel fading and multi-path information.

Abstract: This invention discloses a channel estimation method for partial IC in TD-SCDMA intra-frequency cell, Specifically IC or de-correlation multi-user detection is utilized. Partial IC is implemented to realize the joint detection of the channel in several intra-frequency cells. As to n cells, the detailed procedures go as follows: At first, n 2×128 memories are established, just as s1, s2, s3, . . . sn, in order to store the complex serial. Midamble codes of the received signal constitute the 128-chip data. Step 1: The data taken from Midamble codes of the received signals undergo the Partial IC process of the residual past in the first cell. The process of channel estimation in the first cell is undertaken. Afterwards, the received signals of UE from the 1st cell are recovered.

Abstract: The present invention provides systems and methods for faster acquisition and more stable tracking of spread spectrum signals with lower computational load requirements. Instead of the present day practice of using only the Prompt correlator, the systems and methods of the invention use the sum of the powers of all the correlators of a channel to determine the acquisition or tracking of the signal. These systems and methods improve the signal acquisition speed resulting in a reduced Time-To-First-Fix (TTFF). Further, these systems and methods improve the acquisition and tracking sensitivity of the receiver.
