Master-slave and rate configurable SC-FED system baseband frame structure

Abstract

The invention relates to a master-slave and rate configurable SCFED system baseband frame structure, which is characterized in that a user only needs to define master-slave attribute requirements andrate requirements of communication equipment at the beginning of communication, then configures the equipment as a master station or a slave station as required according to prompt of a software interface, and configures the equipment as a slave station after equipment attribute configuration is completed. Corresponding rate parameters are configured according to respective rate requirements of the master station and the slave station, so that uplink / downlink transmission rates of any requirements can be obtained, and a communication link can be established according to user requirements by restarting equipment. When the master-slave attribute requirement or the rate requirement of the user needs to be changed, the master-slave attribute configuration and the rate parameter configuration of the equipment only need to be carried out again according to the new requirement, and the requirement can be met. Different rate requirements and use scene requirements of different users or the same user can be flexibly and quickly met without additionally increasing the cost.

Description

technical field [0001] The present invention relates to a SC-FED system baseband frame structure with master-slave and rate configurable, in particular, the present invention relates to a device master suitable for TDD SC-FED system in the field of wireless communication, in the space-earth communication link. Dependency, uplink and downlink transmission rate can be flexibly configured according to the needs of the baseband frame structure. Background technique [0002] In recent years, with the rapid development of wireless communication technology, high bandwidth and high speed have become the focus of people's increasing attention. Therefore, it is more and more important to solve the problems of frequency selective fading and time selective fading caused by channel multipath effect and Doppler effect in broadband wireless communication signal transmission. In order to solve this problem, the application of OFDM (Orthogonal Frequency Division Multiplexing) and SC-FDE (Si...

Problems solved by technology

[0004] In order to solve the drawbacks that the existing baseband frame structure cannot meet the rate requirements of different application scenarios and the multi-rate requirements of the same user, the present invention proposes a master-slave and rate configurable system that can independently configure the rate and the master-slave properties of the device. The baseband frame structure of the SC-FED system, when the user's master-slave attribute requirements or rate requirements need to be changed, it only needs to re-configure the master-slave attributes and rate parameter configurations according to the new requirements to meet the requirements.
