Abstract

The invention provides a resource optimization method and device in baseband processing, and electronic equipment, and relates to the technical field of communication. The method and the device are applied to a DVB-T2 system sending end. The method comprises the following steps of acquiring data to be transmitted, writing the data to be transmitted into an RAM according to a cell interleaved writing rule, and reading the written data to be transmitted from the RAM according to a time interleaved output rule. According to the resource optimization method and device in the baseband processing, and the electronic equipment which are provided by the invention, cell interleaving and time interleaving are combined, so that the occupied RAM resources are reduced, and the running speed of the T2 system is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource optimization method, device and electronic equipment in baseband processing. Background technique [0002] DVB (Digital Video Broadcasting, Digital Video Broadcasting)-T2 is the second-generation European digital terrestrial television broadcasting transmission standard, and the highest TS stream (Transport Stream) transmission rate supported within the 8MHz spectrum bandwidth is about 50.1Mbit / s. The service to be transmitted is transmitted through the DVB-T2 system (hereinafter referred to as the T2 system). [0003] In the prior art, the transmitting end of the T2 system usually includes four consecutive modules of constellation mapping, constellation rotation, cell interleaving, and time interleaving, which are used to perform baseband processing on the data to be transmitted. Such as figure 1 As shown, the serial-to-parallel converted data to be t...
