摘要： A method for controlling an input signal of a power amplifier is provided. The method comprise applying CFR to the input signal to obtain a processed input signal; determining a minimum CFR threshold; comparing the peak power of the power amplifier and an allowable peak power; and if the peak power is below the allowable peak power, determining a final CFR threshold by increasing the minimum CFR threshold, or if the peak power is not below the allowable peak power, reducing the average output power until peak power reaches the allowable peak power.

摘要： A method and system for creating a histogram of oriented occurrences (HO2) is disclosed. A plurality of entities in at least one image are detected and tracked. One of the plurality of entities is designated as a reference entity. A local 2-dimensional ground plane coordinate system centered on and oriented with respect to the reference entity is defined. The 2-dimensional ground plane is partitioned into a plurality of non-overlapping bins, the bins forming a histogram, a bin tracking a number of occurrences of an entity class. An occurrence of at least one other entity of the plurality of entities located in the at least one image may be associated with one of the plurality of non-overlapping bins. A number of occurrences of entities of at least one entity class in at least one bin may be into a vector to define an HO2 feature.

摘要： The present disclosure discloses a method for multi-homing path selection of a stream control transmission protocol (SCTP). The method includes the following steps of: starting quality evaluation of paths; calculating a quality evaluation value of each path; comparing the quality evaluation value of each path; and selecting a path with the highest quality evaluation value to transmit a data message. The present disclosure also discloses an apparatus for multi-homing path selection of an SCTP. By adopting the method and the apparatus, a network selects the path with the highest quality evaluation value to transmit a data message. As long as path faults affect the transmission efficiency, other path with better quality is selected for transmission, thus the capability of the network of dealing with all kinds of path faults can be improved, and the data transmission speed and quality are further improved.
