Abstract: A Delta-Sigma analog-to-digital converter and a method thereof are provided. According to a non-overlapping clock signal, the Delta-Sigma analog-to-digital converter performs an integration process on the difference between a plurality of input signals and the corresponding feedback signals to generate an integrated signal. Then, according to a selecting signal, the integrated signal is selectively output. Afterward, according to a latch signal, the selectively output integrated signal is quantized and latched by only one quantizer, thereby generating a digital output signal correspondingly. Accordingly, by using only one quantizer, the present invention can have the same function as the prior art which uses a plurality of quantizers, thereby decreasing the occupied chip area.

Abstract: 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.

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.
