Problems solved by technology

First of all, this is a waste of resources; second, since multiple sets of scrambling codes are used for scrambling, the transmitter needs to inform the receiver which set of scrambling codes is selected, which takes up system overhead and makes the control process complicated

Abstract

The invention provides a control signling transmission method and a control signling transmission device. The method comprises the steps of block-coding a signaling bit, modulating the block-coded signaling bit, repeating and sorting modulated symbols according to specified rules and transmitting the repeated and sorted symbols. With the control signling transmission method and the control signling transmission device, better signal uniformity is achieved, and the influence of abnormal direct-current jitter of a transmitting end due to poor control signaling uniformity when a digital signal is transmitted to an analog circuit can be minimized.

Description

technical field [0001] The present invention mainly relates to the field of microwave communication transmission, in particular to a method and device for transmission of control signaling. Background technique [0002] figure 1 A system diagram of the classic originating zero-IF scheme in communication and transmission systems is described. Typically, this scheme mixes DC in the output signal portion of an analog circuit. The main reason for the generation of DC is the leakage of the local oscillator during the analog mixing process. After many experiments, it is found that the randomness and uniformity of the baseband digital signal sent to the DAC (digital-to-analog converter) will affect the DC change there. The more uniform and random the signal, the more constant the DC. Therefore, it is necessary to ensure the randomness and uniformity of the signal sent into the analog circuit. [0003] figure 1 The baseband digital signal before the DAC is sent to the DAC, and ...
