Description: The most straightforward approximation is the standard Gaussian approximation, where the MAI is approximated by a Gaussian random variable. This approximation is simple, however it is not accurate in general. In situations where the number of users is not large, the Gaussian approximation is not appropriate. In-depth analysis of must be applied. The Holtzman?s improved Gaussian approximation provides a better approximation to the MAI term. The approximation conditions the interference term on the operation condition of each user. Platform: |

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: This Paper is concerned with the study of the performance of DPSK (differential phase shift keying)
Modulation Technique using AWGN(Additive white gaussian noise) channel. The DPSK has remarkable
features such as limited bandwidth and constant envelope, which are of importance for mobile communication
systems for providing the output according to our needs and requirement. In this study we evaluated the Bit
error rate performance of the CDMA system by designing the CDMA system using SIMULINK Tool of the
MATLAB software and study the performance characteristics of DPSK modulated CDMA system which are
helpful for raising the level of present day communication systems, In order to design our DPSK modulated
CDMA system we varied only modulation blocks of simple CDMA transmitter and receiver sections. Platform: |
