Problems solved by technology
[0003] The existing LTE base station downlink baseband processing method is designed based on the processing sequence specified in the protocol, and the implementation process is simple and clear. However, the entire processing process is mostly completed in the symbol domain, which consumes a large amount of calculation and storage resources, and the multi-cell processing support capability is low.

Embodiment Construction
[0036] The basic idea of the technical solution of the present invention is: divide the entire processing process into two parts, the bit domain and the symbol domain, and in addition to the original bit domain processing, part of the symbol domain processing is equivalently completed in the bit domain, specifically including:
[0037] A. The data interface serially receives the bit data to be sent downlink by each cell, and performs bit field processing on the bit data. The bit field processing includes performing precoding processing on the bit data that can be equivalent to bit operations, and buffering the bit field processed bit data;
[0038] B. Extract the bit data of each cell in parallel from the cache, convert the bit data into symbol data, and perform symbol domain processing on the symbol data.
[0039] In order to make the technical principles, features and technical effects of the technical solution of the present invention clearer, the solution of the present ...

The invention provides an LTE base station downlink base-band processing method. The method includes the steps that first, a data serial interface receives bit data to be sent by all cells in a downlink mode and carries out bit domain processing on the bit data, wherein the step of bit domain processing includes the process of precoding processing equivalent to bit operation on the bit data and the process of caching the bit data which have been subjected to bit domain processing; second, the bit data of all the cells are extracted from a cache and converted into symbolic data, and symbol domain processing is carried out on the symbolic data. The invention further provides an LTE base station downlink base-band processing device. Compared with the prior art, the LTE base station downlink base-band processing method and the LTE base station downlink base-band processing device can save processing resources of a base station greatly.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a downlink baseband processing method and device of an LTE base station. Background technique [0002] With the development of a new generation of wireless communication technology and the increase of bandwidth, higher and higher requirements are put forward for the baseband processing speed of communication equipment. Therefore, communication devices need to meet the ever-increasing demands for bandwidth and processing speed. The increase of bandwidth and the improvement of processing speed need to consume more processing resources. In the case of limited processing resources, it is required that the processing resources required by communication devices to complete a process should be as small as possible. In addition, on the basis of meeting the requirements of baseband processing speed, the design cost of communication equipment also needs to be reasonab...
