Title:
SIGNAL PROCESSING METHOD AND MICROWAVE COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/000120
Kind Code:
A1
Abstract:
Provided in the embodiments of the present invention are a signal processing method and a microwave communication device, comprising: an indoor unit (IDU) and an outdoor unit (ODU); the IDU comprises: an encoder, an interpolation module and a first digital signal interface; the ODU comprises: a second digital signal interface and an ODU output control module; the encoder is used for encoding data to be transmitted so as to obtain a first digital signal; the interpolation module is used for performing variable-rate interpolation processing on the first digital signal so as to obtain a second digital signal, and for outputting the second digital signal to the ODU output control module by means of the first digital signal interface and the second digital signal interface; the ODU output control module is used for performing digital pre-distortion (DPD), digital-to-analog conversion, modulation and power amplification processing on the second digital signal so as to obtain a first analog signal. Digital signal transmission implemented between an IDU and an ODU reduces attenuation of an analog signal during transmission, thereby reducing a need for amplifying the analog signal so as to offset attenuation loss, thus reducing cost.
