Номер: CN103166743A
Автор: Liang Xianfeng, Zhang Jinzhou, Xiong Yuming, An Junshe
Принадлежит:

The invention provides a base band digital signal encoding modulation integrated system comprising a cascade encoding module, a PCM/PSK/PM modulation module and a BPSK/NRZ modulation module. The system is characterized by further comprising a control subsystem used for controlling encoding modulation modes of the cascade encoding module, the PCM/PSK/PM modulation module and the BPSK/NRZ modulation module, wherein the subsystem further comprises an interface module, a first multiplexer, an SRRC-OQPSK modulation module, a data distributor, a multiplexer and a control logic module. The first multiplexer is used for selecting data in one path from two path data output from the interface module and outputting the data to a post-stage circuit which is the cascade coding module. The system is used for completing reed-solomon (RS) coding interface data selection of base band data and coding framing, and can correspondingly select different modulation mode functions according to different transmission ...
