(March 2013) (Learn how and when to remove this template message) In digital transmission, the number of bit errors is the number of received bits of acceptable bit error rate a data stream over a communication channel that have been altered due to bit error rate measurement noise, interference, distortion or bit synchronization errors. The bit error rate (BER) is the number of bit errors per bit error rate pdf unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. BER is a unitless performance measure,

often expressed as a percentage.[1] The bit error probability pe is the expectation value of the bit error ratio. The bit error ratio can be considered as an approximate estimate of the bit error probability. This estimate is accurate for a long time interval and a high number of bit errors. ContentsExampleEdit As an example, assume this transmitted bit sequence: 0 1 1 0 0 0 bit error rate calculator 1 0 1 1 and the following received bit sequence: 0 0 1 0 1 0 1 0 0 1, The number of bit errors (the underlined bits) is, in this case, 3. The BER is 3 incorrect bits divided by 10 transferred bits, resulting in a BER of 0.3 or 30%. Packet error ratioEdit The packet error ratio (PER) is the number of incorrectly received data packets divided by the total number of received packets. A packet is declared incorrect if at least one bit is erroneous. The expectation value of the PER is denoted packet error probability pp, which for a data packet length of N bits can be expressed as p p = 1 − ( 1 − p e ) N {\displaystyle p_{p}=1-(1-p_{e})^{N}} , assuming that the bit errors are independent of each other. For small bit error probabilities, this is approximately p p ≈ p e N . {\displaystyle p_{p}\approx p_{e}N.} Similar measurements can be carried out for the transmission of frames, blocks, or symbols. Factors affecting the BEREdit In a communication system, the receiver side BER may be affected by transmission channel noise, interference, distortion, bit synchronization problems, atte

AUTHOR'S COMMENTS The purpose of this book is to present the engineering considerations necessary for the comprehension of modern telecommunication measurement and related instrumentation and analysis techniques. I wish to emphasize that this is not an academic book in the sense of analytical communications or measurement theory. Rather, it stresses the measurements, experimental analysis and instrumentation problems related to communications systems. PUBLISHER'S COMMENTS This book provides a strong foundation for understanding the special problems associated with testing modern communications systems. Its original publication anticipated the needs of communications engineers, setting a foundation for current work. The book's continued availability assures that new engineers will have access to a key reference text in this important area of technology.

can't address the unique requirements of serial link analysis, which include simulating millions of bits worth of behavior, accurately representing http://www.sisoft.com/products/quantum-channel-designer.html broadband interconnect characteristics and modeling the equalization / clock recovery characteristics of specific SerDes IP. SiSoft's Quantum Channel Designer (QCD) is a dedicated, system-level design and analysis environment for multi-Gigabit serial links. QCD incorporates the latest frequency-domain, time-domain and statistical techniques to provide accurate analysis of end-to-end serial link behavior. Designers capture bit error their designs graphically and experiment with different physical layout / equalization strategies to predict how design alternatives will affect operating margins and the link's Bit Error Rate (BER). Graphical Design CaptureQuantum Channel Designer lets designers capture channel designs graphically, combining SerDes IP blocks with a mixture of discrete elements, lossy transmission bit error rate lines, sub-circuit and S-parameter blocks. Designers set up simulation experiments from the GUI by declaring design variables and values to be studied. Standards-based models for SerDes IP provide Plug and Play operation - users place TX/RX devices on their schematic and QCD exposes model settings for vendor-specific SerDes IP that can be controlled from the GUI. Progressive AnalysisQuantum Channel Designer allows designers to trade off simulation speed versus accuracy. Network characterization models the behavior of the unequalized analog network, allowing tradeoffs in the analog channel design to be quickly evaluated. Statistical and time-domain analyses include SerDes equalization and clock recovery modeling to predict the link's end-to-end behavior. Crosstalk analysis includes the effect of aggressor signals on overall channel bit error rate. Solution Space AnalysisOptimizing a serial link design requires evaluating dozens of design variables and their possible combinations, which can require thousands of simulations for a single set of design decisions.
