The common-mode (CM) signal in wireline transmission systems has proven to provide valuable information exploited for mitigating narrowband noise at the receive side. In this paper, we focus on the case of broadband noise. Treating the CM signal as an additional receive signal, we investigate the capacity of the copper cable channel for different levels of(More)
This paper presents an optimized turbo equalizer based on Laot’s turbo equalization scheme by means of soft intersymbol interference (ISI) cancellation. Due to Berrou’s turboprinciple, common turbo equalization schemes use the extrinsic information as a-priori input for the equalizer. In contrast to this, we propose the use of the full soft output channel(More)
Exponentially weighted recursive least-squares (RLS) algorithms are commonly used for fast adaptation. In many cases the input signals are continuous-time. Either a fully analog implementation of the RLS algorithm is applied or the input data are sampled by analog-to-digital (AD) converters to be processed digitally. Although a digital realization is(More)
This paper presents techniques for digital interpolation in the passband domain, exemplarily for a carrierless amplitude modulation/phase modulation (CAP) transmission system. Well-known techniques for designing baseband interpolation filters are extended to signal processing at nonzero center frequencies. The resulting filters are either real- or(More)
− This paper introduces an algorithm for blind adaptation of decision feedback equalizers (DFE), which is applied for equalization in the passband domain. The transmission scheme, which is assumed to be unknown at the receiver side, can either be carrierless amplitude/phase (CAP) modulation or quadrature amplitude modulation (QAM). As the input signal of(More)
