“…Firstly, the communication protocol data rate must be fast enough to transfer the error voltage data corresponding to the current switching period, and it must allow sufficient time to calculate the duty cycle for the next switching period. The protocol must also detect and handle transmission errors [30] to prevent miscalculation of the duty cycle. Dedicated signal lines for clock and auxiliary signals must be avoided to minimize the number of required couplers.…”

Abstract-An efficient high-speed bi-directional data transmission scheme for isolated AC-DC and DC-DC switched mode power converters is presented. The bi-directional scheme supports fast, efficient and reliable transmission of digitally encoded data across the isolation barrier and enables primary side control, allowing effective start-up and a simple interface to system controllers. Another key feature is that the bi-directional communication is independent of coupler gain and degradation and only the minimum number of couplers is required. The digital interface can also be used to transmit auxiliary signals between both sides. For test purposes, the scheme has been implemented on FPGAs and verified using a custom-built SMPC board.

“…2 It follows that the joint error statistics are entirely determined by the "nesting" properties of the channel's worst-case patterns, which are in turn determined by the channel's signature. The pattern nests if and some shifted versions of , each shifted by at most symbols relative to the first pattern, align exactly on the overlapping symbols.…”

“…In contrast, letting = 0:125, the error region includes second-to-worst-case ISI. Based on the marginal error probability of p = 5:9 2 10 and assuming independent errors, the desired event's probability is given by p (1 0 p ) = 1:5 2 10 . Yet, the proportion of 10-symbol blocks with two errors calculated accurately is now five times higher, namely 7:3 2 10 .…”

“…The RocketIO transceivers employ linear equalizers in the form of transmit pre-emphasis and receive high-pass filter. Equalization settings are explored exhaustively to yield the lowest uncoded error rates, shown in Table I 1) Testing the Error Independence Hypothesis: Given a prior lack of suitable performance estimation methods for coded high-speed links, it is common practice to focus on marginal error statistics and ignore the effect of error correlation on code performance.For instance, in [1] and [2], the improvements achieved by the proposed codes are computed based on the assumption that the errors on distinct symbols are independent.

“…Despite several recent efforts [1], [2], the topic of channel coding for high-speed links remains largely unexplored due to a lack of suitable analysis and simulation frameworks. The residual intersymbol interference (ISI), coupled with noise and other circuit impairments, significantly obscures the performance picture and renders both the theoretical and computational approaches more arduous.…”

Abstract-While channel coding is a standard method of improving a system's energy efficiency in digital communications, its practice does not extend to high-speed links. Increasing demands in network speeds are placing a large burden on the energy efficiency of high-speed links and render the benefit of channel coding for these systems a timely subject. The low error rates of interest and the presence of residual intersymbol interference (ISI) caused by hardware constraints impede the analysis and simulation of coded high-speed links. Focusing on the residual ISI and combined noise as the dominant error mechanisms, this paper analyzes error correlation through concepts of error region, channel signature, and correlation distance. This framework provides a deeper insight into joint error behaviors in high-speed links, extends the range of statistical simulation for coded high-speed links, and provides a case against the use of biased Monte Carlo methods in this setting. Finally, based on a hardware test bed, the performance of standard binary forward error correction and error detection schemes is evaluated, from which recommendations on coding for high-speed links are derived.

This paper addresses the problem of finding, evaluating, and selecting the best set of codewords for the 4b/10b line code, a dependable line code with forward error correction (FEC) designed for real-time communication. Based on the results of our scheme [1], we formulate codeword search as an instance of the maximum clique problem, and enumerate all candidate codeword sets via maximum clique enumeration as proposed by Eblen et al. [2]. We then measure each set in terms of resistance to bit errors caused by noise and present a canonical set of codewords for the 4b/10b line code. Additionally, we show that maximum clique enumeration is #P-hard.
