The present disclosure discloses a method and an apparatus for generating a map, relating to a field of intelligent transportation technologies in the field of computer technologies. The method includes the following. A street view image corresponding to a target road is obtained. The street view image is input into a preset deep learning model to obtain data of a candidate isolation belt corresponding to the street view image. The data of the candidate isolation belt includes information of the candidate isolation belt and a probability corresponding to the information of the candidate isolation belt. The information of the candidate isolation belt is corrected based on a preset correction strategy and the probability to obtain information of a target isolation belt. An icon corresponding to the information of the target isolation belt is added on a base map including the target road to generate a map.

Method and apparatus for generating map

The present disclosure provides a digital pre-distortion transmitter and a method for controlling the same, which increase the efficiency of the power amplifier and improve the linearity of the transmitter. The digital pre-distortion transmitter includes: a pre-distortion unit configured to update a pre-distortion coefficient required by pre-distortion processing, and perform the pre-distortion processing on a baseband signal; a signal process and transmit unit configured to perform signal processing on the pre-distortion-processed baseband signal and transmission thereof; and a feedback signal process unit configured to process a feedback signal of the signal transmitted by the signal process and transmit unit, so as to supply a dynamic drain voltage to a power amplifier in the signal process and transmit unit by using the processed feedback signal; and, the pre-distortion unit updates the pre-distortion coefficient by using the feedback signal processed by the feedback signal process unit.
