What is error probability meaning?
In statistics, an error probability is the frequency with which a certain probabilistic testing procedure will lead to a type I error or a type II error. In other words, it is the rate of occurrence of an error in a hypothetical infinite repetition of the procedure.
Which modulation technique have the same bit and symbol error probability Mcq?
Which modulation technique have the same bit and symbol error probability? Explanation: BPSK, DPSK, OOK and non coherent FSK have same bit and symbol error probability.
What does √ 2ps represent?
What does √(2Ps) represent? Ans. √(2Ps) is equal to amplitude A of the carrier .
Which has higher error probability performance?
Which has higher error probability performance? Explanation: Bipolar base-band signalling has high error probability performance than the others.
What is probability error of FSK?
The probability of error for coherent FSK is Pϵ = erfc√ E η .
How to reduce the error probability of BPSK signal?
The error probability can only be made smaller (for fixed energy per bit) by allowing more than two waveforms for transmitting information. VI-2 BPSK Modulator b t 2Pcos 2πfct Modulator s t n t r t Figure 33: Modulator for BPSK To mathematically described the transmitted signal we define a pulse function pT t as pT t 1 0 t T 0 otherwise. t 1 pT
What is the minimum error probability of a binary modulation?
Any binary modulation where the two signals are antipodal gives the minimum error probability (for fixed energy) over any other set of binary signals. The error probability can only be made smaller (for fixed energy per bit) by allowing more than two waveforms for transmitting information. VI-2 BPSK Modulator b t 2Pcos 2πfct Modulator s t n t r t
What is the conditional probability distribution function of BPSK modulation?
The conditional probability distribution function (PDF) of for the two cases are: Figure: Conditional probability density function with BPSK modulation Assuming that and are equally probable i.e. , the threshold 0forms the optimal decision boundary. if the received signal is is greater than 0, then the receiver assumes was transmitted.
