In this paper, a framework to study the error performance of multiuser diversity in point-to-multipoint (PMP) MIMO transmit antenna selection networks is presented. Based on this framework, we derive the exact closed-form symbol error rate formula in terms of antenna selection gain, MIMO ...
In calculating the average symbol error rate with no closed form formula, numerical computation of the integral may be very difficult. To circumvent this problem, we resort to bounds, which can provide good approximations, and for low error probabilities, tight upper bounds can be developed. The...
Can u please tell me the formula/expression of BER(bit error rate) in terms of SNR ( signal to noise ratio) for QPSK of AWGN channel. The above mention expression is for Symbol error rate. and then why this formula for BER of AWGN avowed Pb=Q(√(2Eb/No)) and SER Ps≈2Q(√(Es...
As an application, the probability of error of single input single output communication systems using different modulation schemes with an α-stable perturbation is studied. In more details, a generic formula is derived for generalized fading distribution, such as the extended generalized-k distribution...
Total symbol error probability Given that we have computed the individual symbol error probability for each of the three types of constellation points, to find the joint symbol error rate we compute the average error i.e. Pluging in the equations, ...

For all other signals, there is no "easy" formula to help determine the minimum span that achieves published specifications. However, it can be ensured that the measurement achieves published specifications by selecting a Frequency Span that contains all energy of the transmitted signal. ...
Mathematicians often wish to discuss mathematical objects, so in a mathematics text the subject of a sentence can be a mathematical symbol or formula. For instance, □ is a box symbol. “□” is a box symbol. x is a variable. ”x” is a variable. ”x = y” is an equation. are al...
