A display device includes at least one display module and a backlight module. The display module includes display units and N driving chips. The N driving chips are arranged along a first direction and electrically connected to the display units. The display units are connected and arranged in N rows in the first direction and M columns in a second direction. N and M are respectively greater than or equal to 1. The backlight module includes a light bar assembly adapted to be disposed below a column of the M columns of the display units farthest from the driving chips, and a length of the light bar assembly corresponds to that of the display units along the first direction. The light bar assembly includes at least one first light bar unit. A length of each first light bar unit is X times the length of each display unit along the first direction, and X is greater than or equal to 1.

A method of noise mitigation in a multi-carrier communication system includes receiving a signal from a decision device, determining whether synchronization symbol update is enabled, updating at least one of frequency-domain equalizer (FEQ) coefficients or digital echo canceller (DEC) coefficients in synchronization symbol periods if the synchronization symbol update is enabled, determining whether data symbol update is performed if the synchronization symbol update is not enabled, determining whether a flag associated with the signal is set if the data symbol update is not performed, and updating at least one of FEQ or DEC coefficients associated with the signal in synchronization symbol periods if the flag is set.

Method for impulse noise mitigation

A collision detection method for a multiple access communication system is disclosed. By using the error term of a time-domain equalized signal as a detection source, an operation on the error term can be performed to determine whether collision occurs. For example, the mean square error and/or maximum value of the real part and/or imaginary part of the error term can be calculated or selected to distinguish the collision and non-collision situations. A collision detection apparatus for a multiple access communication system is also disclosed. The collision detection apparatus utilizes an existent adaptive equalizer and signal processing device for obtaining received information data bits to obtain the error term. The error term is further processed by a mean-square-error or maximum-absolute-value operator to determine the collision status.

A digital-to-analog converting method operating under two clock signals of different periods is disclosed. The method includes steps of monitoring a phase relationship between the two clock signals; starting transmission of a plurality of pre-stored series of waveform samples in response to each rising edge of the first clock signal, wherein a phase difference is present between every two adjacent series of waveform samples; outputting the waveform samples of each series in response to rising edges of the second clock signal; and selecting one of the plurality of pre-stored sets of waveform samples to be converted into an analog signal according to the phase relationship. The various pre-stored series of waveform samples having therebetween phase differences are optionally used for phase compensation so as to reduce the clock jitter between the two clock signals. A digital-to-analog converter for implementing the above-mentioned method is also disclosed.
