Bit Error Rate Calculation
we? In a QPSK modulation scheme, 2 bits would be mapped into one symbol. Mainly 00 01 10 and 11. Thus, the symbol error rate would be the error associated with the symbols. Lets say we transmit a symbol 00 and there are some noise is in the system. The decoding part decodes the symbol to 11 instead of the actual symbol of 00. The Symbol error is 1 for this case as there's just a single symbol error but the bit error is 2 since both of the bits in the symbol is not the correct bit. For you to plot the BER vs SNR curve, you would need to know the number of bits in the symbol itself. Else, you would just be plotting the SER + Post New Thread Please login « need information about problems need to be solve | MIMO system exploiting partial channel » Similar Threads Explanation of the Shannon's law equation (1) Frame Error rate and Pair-wise Error Probability (3) [Help ] Symbol rate Estimation (1) how symbol and bit error prob. are related.

Thought that SER & BER are the same symbol error rate but did my research to find that BER is $\dfrac{1}{\log_2(M)}$ of SER...(could you please confirm this?) Also found SER for: 4QAM to be: $\text{erfc}\sqrt{\dfrac{E_b}{2N_0}}$ and that of 16QAM to be: $\dfrac{3}{2} \text{erfc}\sqrt{\dfrac{E_b}{10N_0}}$ Are these values correct? Still have problems to find SER for 32QAM... Hope you can help. derivation share|improve this question edited May 13 '14 at 19:26 jojek♦ 6,70041444 asked May 13 '14 at 19:14 John Smith 112 Take a look at this question and its answers: dsp.stackexchange.com/questions/15996/… –Matt L. May 13 '14 at 19:15 still can't understand the relation (not mentioned anywhere in those questions & answers). Also 16QAM & 32QAM weren't covered in that question.. –John Smith May 13 '14 at 19:23 did my research, cant use that formula when dealing with an odd number of bits per symbol, for which bits per symbol for 32QAM is 5... –John Smith May 13 '14 at 19:41 @JohnSmith: The problem is that there isn't a standard definition of what 32-QAM is. For non-square QAM modulations, there are multiple geometries in which you could implement the constellati
Formulae Manufacture Satellites Telecoms & networks Jobs RF Technology & Design BER Bit Error Rate Tutorial and Definition - bit error rate, BER is used to quantify a channel carrying data by counting the rate of errors in a data string. It is used in telecommunications, networks and radio systems. Bit Error Rate Tutorial Includes Bit error rate basics / tutorialBit error rate testing Bit error rate, BER is a key parameter that is used in assessing systems that transmit digital data from one location to another. Systems for which bit error rate, BER is applicable include radio data links as well as fibre optic data systems, Ethernet, or any system that transmits data over a network of some form where noise, interference, and phase jitter may cause degradation of the digital signal. Although there are some differences in the way these systems work and the way in which bit error rate is affected, the basics of bit error rate itself are still the same. When data is transmitted over a data link, there is a possibility of errors being introduced into the system. If errors are introduced into the data, then the integrity of the system may be compromised. As a result, it is necessary to assess the performance of the system, and bit error rate, BER, provides an ideal way in which this can be achieved. Unlike many other forms of assessment, bit error rate, BER assesses the full end to end performance of a system including the transmitter, receiver and the medium between the two. In this way, bit error rate, BER enables the actual performance of a system in operation to be tested, rather than testing the component parts and hoping that they will operate satisfactorily when in place. Bit error rate BER definition and basics As the name implies, a bit error rate is defined as the rate at which errors occur in a transmission system. This can be directly translated into the number of errors that occur in a string of a stated number of bits. The definition of bit error rate can be translated into a simple formula: If the medium between the transmitter and receiver is good and the signal to no
