摘要: 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. The channel of the other cells is estimated from the received signals and the received signals of corresponding Midamble code is recovered to repeat the above procedures, until the completion of the process of the received signal, and it comes to Step (n+1). Iteration once is finished from Step 1 to Step (n+1), in which n processes are involved and one process is correspondent to one cell. The iteration after m times will finalize the channel estimation.

摘要: 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.
