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

Frequency Stability, Frequency Drift and Phase Instability 5.1 Frequency Stability 5.2 Frequency Drift 5.3 Phase Instability 6 Notes Sensitivity Sensitivity is a concept that refers to the minimum usable http://wiki.yatebts.com/index.php/Radio_Performance_Concepts signal level at the receiver. In the case of the GSM handset, the sensitivity level is around -100 dBm, while for the BTS this level reaches approximately -106 dBm. This difference appears due to the higher quality electronics used in the basestation. Signal-to-Noise Ratio (SNR) Signal-to-noise ratio is a method that calculates the ratio of the desired signal power to the background noise error rate power and is expressed in decibels[1]. Any ratio higher than 1:1, or greater than 1 dB, means that there is more signal than noise. Receiver Error Rates and Error Correction Coding Bit Error Rates In digital transmissions, bit errors represent the number of alerted bits entering a data stream through a communication channel. Bits can be distorted by noise, interference or bit synchronization errors. bit error rate The bit error rate is the ratio between the bit errors and the total number of transferred bits during a particular time. A receiver's bit error rate can be affected by noise, interference or multipath fading. To improve it, one must use a more robust modulation scheme that would lead to transmitting a stronger signal, or to apply error correction coding schemes[2]. There are two types of bit error rates: transmission bit error rate – the number of incorrect bits divided by the total number of transmitted bits information bit error rate – the number of decoded bits that remain incorrect after applying error correction schemes divided by the total number of decoded bits Usually, the transmission bit error rate is greater than the information bit error rate. Error Correction Coding Error correction coding is a method of controlling errors during data transmissions over noisy channels of communication, using redundant message encoding. The main purpose of error correction coding is to allow the receiver to spot a number of errors during the message transmission and to correct them without retransmission and, as such, without a reverse channel for the retransmission[
