Bit Error Rate analysis of an Extended Receiver for Rectangular PAM. The performance of a digital communication system in the presence of additive white Gaussian noise (AWGN) can be assessed by the measurement of the bit error rate (BER). The Simulink model provided is a rectangular polar pulse amplitude modulation (PAM) baseband system with an AWGN channel and an extended sample and hold receiver with a low pass filter. An extended receiver has an odd number of sample and hold circuits. What remains to be answered is if such a receiver would provide a more desirable BER than that of a simple S/H receiver.

Asynchronous Transfer Mode (ATM) is a connection-oriented, packet-switched technology. The packets that are switched in an ATM network are of a fixed length, 53 bytes, and are called cells. The cell size has a particular effect on carrying voice traffic effectively. The ATM Adaptation Layer (AAL) sits between ATM and the variable-length packet protocols that might use ATM, such as IP.
匹配滤波器的实现。主要是通过fft变化使输出自相关最大,在通过滤波器。(Matched filter implementation. Mainly through changes in the output autocorrelation fft the largest through the filter.)
This thesis presents simulation data on array operation in wideband communication systems. It is shown that array structures with closer inter-element spacing outperform structures with much larger inter-element spacing. It is also shown that circular structures outperform linear structures. This performance dierence between the classications of arrays is due largely to the circular array s ability to handle high levels of interference. Even though a diversity combining scheme (MRC) was used in the simulator, the arrays provided interference rejection capabilities due to the closely spaced antenna elements.
