A Novel Selection Diversity Technique for MSK using Hardlimiter Output
نویسنده
چکیده
Often mobile radio channels encounter severe fading obstructions. A link stabilization may be achieved using diversity. In this contribution, a selection diversity technique for MSK allowing synchronization as well is proposed. With the aid of characteristic functions, its properties are derived. Using both analysis and simulation, the criteria are compared and show similar performance. Both criteria almost yield ideal selection diversity performance.

متن کاملCapacity and performance analysis for hybrid selection/maximal-ratio combining in Nakagami fading with unequal fading parameters and branch powers
We consider a hybrid selection/maximal-ratio combining (HS/MRC) diversity system and assume independent Nakagami fading on the diversity branches with unequal fading parameters and unequal signal-to-noise ratios (SNR’s). We use the virtual branch technique and two series expressions for the characteristic function (CF) of the sum of independent gamma random variables to derive closed-form expre...

Intrusion detection systems (IDS) by exploiting Machine learning techniques are able to diagnose attack traffics behaviors. Because of relatively large numbers of features in IDS standard benchmark dataset, like KDD CUP 99 and NSL_KDD, features selection methods play an important role. Optimization algorithms like Genetic algorithms (GA) are capable of finding near-optimum combination of the fe...

Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...
