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

Provided are a method and device for increasing bit-level throughput of transmitter of an LTE Base Station (BS) in the present invention. And the method comprises: adding Transmission Blocks (TB) CRC24a and dividing the Code Blocks (CBs) during the course of the bit-level process in transmitter of an LTE BS. During the course of bit-level process in transmitter of an LTE BS, after dividing the CBs, the method further comprises: assorting, one by one, the divided CBs according to the size; dispatching the assorted CBs in turn of the plurality of categories to perform Turbo coding and rate matching for the CBs. The whole data delay of the BS is able to decreased, so as to increase the whole bit-level throughput of transmitter of the BS.

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...
