Description: 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.-Bit Error Rate analysis of an Extended Receiver for Rectangular PAM.

Description: 分析了在超宽带通信系统中的扩频干扰，并用两种通用的调制技术实现了对提出的抗干扰方法的仿真-he ultra wideband (UWB) interference to direct
sequence spread spectrum (DSSS) receiver is analyzed. Two
popular UWB modulation schemes, the time hopping pulse
position modulation (TH-PPM) and time hopping pulse
amplitude modulation (TH-PAM), are considered. The pulse
repetition rate (T’RR) of UWB signal and the freqnency hand of
the DSSS play the primary roles in the BER performance of the
DSSS receiver in the presence of UWB interference. The UWB
signal parameters raising the interference to DSSS receiver are
discussed. The characteristics of an aggregation of multiple
UWB signals are somehow different from that of a single UWB
device, especially for the TB-PPM scheme, where discrete
spectral lines maybe exist in the band of DSSS receiver. The
system parameters of TH-PPM such as the modulaiion index
and maximum shift incurred hy the time hopping code
determine the amplitude of the discret

Description: Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers,
one exactly 90 degrees out of phase with respect to the other, are used to transmit data over
a given physical channel. One signal is called the I signal, and the other is called the Q signal.
Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase
shift, each can be modulated independently, transmitted over the same frequency band, and
separated by demodulation at the receiver. For a given available bandwidth, QAM enables data
transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation
in the bit error ratio (BER).
