An apparatus and method for improving a symbol error rate of an M-ary phase shift keying (M-PSK) system having a quadrature error are provided. The apparatus includes: a conversion parameter detector that detects a conversion parameter and converts a symbol decision region using the quadrature error and at least one pair of first received symbols; and a converter & determiner converting a pair of second received symbols using the detected conversion parameter, and determining a transmission symbol according to a symbol of the converted pair of second received symbols. An increase in a symbol error rate due to the quadrature error can be prevented and the quadrature error can be easily estimated.

An apparatus and a method for driving a voice coil actuator of a camera are disclosed. In the apparatus for driving a voice coil actuator of a camera, when an input shaping execution unit generates a shaping signal using a resonance frequency of the voice coil actuator to output a drive control signal subjected to input shaping, a drive circuit unit controls an operation of the voice coil actuator connected to a rear end according to the drive control signal using the shaping signal as an initial input. The shaping signal is used for removing resonance of the voice coil actuator and may be one of a 2-step shaping signal, a multi-step shaping signal having 4 or more steps, a linear shaping signal, a toggle shaping signal and the like.

The present invention relates to devices for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart, and related methods of using such closure devices for closing the passageway. The method includes introducing a mechanical closure device into an atrium of the heart and transeptally deploying the closure device across the interatrial septum to provide proximation of the septum secundum and septum primum.
