Abstract

The present invention discloses a signal processing method, and receiving equipment as well as sending equipment thereof. The method comprises: the receiving equipment obtains a channel matrix, obtains an integer matrix according to the channel matrix, and feeds the integer matrix or the transformation matrix of the integer matrix back to the sending equipment to enable the sending equipment to precode the data signals to be sent according to the integer matrix or the transformation matrix of the integer matrix. The embodiment of the present invention can realize a better system performance with fewer feedback quantities.

Description

technical field

[0001] The present invention relates to mobile communication technology, in particular to a signal processing method, a receiving device and a sending device. Background technique

[0002] Multiple Input Multiple Output (MIMO) technology has become a key technology in mobile communication. It increases the spatial freedom without increasing the bandwidth, so that by multiplexing multiple data streams in the spatial dimension, linear The transmission rate of the wireless communication system is greatly increased, which can meet the requirements of high-speed data transmission services. Two basic problems need to be solved in the MIMO system: eliminating the interference between the data streams and equalizing the performance difference between the data streams. Applying the Lattice Reduction (LR) method can solve the above two problems at the same time.

[0003] The first prior art is to use the LR method in the receiving device, and the general process is a...
