schemes PSK, QPSK, OQPSK, MSK, GMSK, and QAM[1,2,3]. The comparison proposes that Bit Error Rate is the fundamental parameter to access the quality of any digital transmission.By describing the basic existing configurations [2,3] and the characteristics of their transmitters and receivers, through MATLAB; we have evaluated them by computer simulation. bit error rate matlab By comparison, it is observed that different modulation techniques struggles neck to neck for getting low BER,but still with the slight change in BER the quality changes many folds(fig-2). If these PSK techniques are used in designing the wireless transmitter, then BER further increases due to system complexity. Therefore there is a requirement of designing the new applications/transmission system having the basis as PSK modulation, so that BER atleast remains constant, if not decreases.

It is used in telecommunications, networks acceptable bit error rate and radio systems. Bit Error Rate Tutorial Includes Bit error rate basics / tutorialBit error packet error rate rate testing Bit error rate, BER is a key parameter that is used in assessing systems that transmit digital data from one location ber repair 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, http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.499.750 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 http://www.radio-electronics.com/info/rf-technology-design/ber/bit-error-rate-tutorial-definition.php 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 noise ratio is high, then the bit error rate will be very small - possibly insignificant and having no noticeable effect on the overall system However if noise can be detected, then there is chance that the bit error rate will need to be considered. The main reasons for the degradation of a data channel and

For example, a transmission might have a BER of 10 to the minus 6, meaning that, out of 1,000,000 bits transmitted, one bit was error rate in error. The BER is an indication of how often a packet or other data unit has to be retransmitted because of an error. Too high a BER may indicate that a slower data rate would actually improve overall transmission time for a given amount of transmitted data since the BER might be reduced, lowering the number of packets that had to be resent. A BERT (bit error rate bit error rate test or tester) is a procedure or device that measures the BER for a given transmission.
