Problems solved by technology

[0005] In the current technology, most of the bit-level delays are solved by increasing the degree of parallelism or increasing the number of processing units, which consumes a lot of resources and has low efficiency, and cannot effectively solve the bit-level delay of the existing OFDM system.

Abstract

The invention discloses a method and device for increasing the bit throughput at a transmitting end of an LTE (Long Term Evolution) base station, wherein the method comprises the following steps: adding CRC24a (cyclic redundancy check 24a) of transmission blocks and segmenting code blocks in a bit processing course at the transmitting end of the LTE base station; after segmenting the code blocks in the bit processing course at the transmitting end of the LTE base station, subsequently classifying the code blocks according to the length of the segmented code blocks; and subsequently scheduling the classified code blocks according to the category to carry out the Turbo coding of the code blocks and the velocity matching of the code blocks, thus the data delay of the integral base station can be reduced to further improve the bit throughput at the transmitting end of the integral base station.

Description

technical field [0001] The invention relates to an LTE base station in the field of digital communication, in particular to a method and a device for increasing bit-level throughput in an OFDM system of an LTE base station. Background technique [0002] With the rapid development of mobile communication, people have higher and higher requirements for the quality of mobile communication and the types of services it provides. LTE (Long Term Evolution) is the evolution of 3G (third generation mobile communication), which meets people's requirements demand, and thus attracted much attention. LTE is 3GPP (3 rd The wireless transmission technology standard proposed by the Generation Partnership Project) organization, it can not only provide high-quality voice services, but also provide multimedia services. [0003] In the LTE system, technologies such as OFDM (Orthogonal Frequency Division Multiplexing), MIMO (Multiple-Input Multiple-Out-put), and Turbo coding are used to impro...
