As the rate of adoption mobile communication technology around world continues to rise, goal using it provide seamless global coverage anyone, anywhere, at any time has become increasingly important. This led major advances in both terrestrial and non-terrestrial satellite networking technology.
Several new architectures are under investigation for cloud radio access networks, assuming distinct splits of functionality among the network elements. Consequently, research on data compression fronthaul is based assumptions that correspond to a wide variety tradeoffs rate, signal distortion, latency, and computational cost. This letter describes method LTE downlink point-to-point linear prediction Huffman coding, which suitable low cost encoding decoding units with stringent restrictions...
The new 3GPP New Radio standard (NR) has the potential of providing high rate mobile broadband services for very long range (resulting in low cost per subscriber) utilizing 3.5 GHz band. In this paper, we discuss techno- economic problems associated with quality to under-served areas and propose best practice enhancements network as well terminals. On terminal side, a solution based on low-cost user deployed booster equipment combined access local spectrum rural hot-spots is proposed. side...
FEC gain in DC-coupled burst mode receivers is limited because of a variance BER between bursts. This characterized an XG-PON1 upstream prototype. It shown that basic tests overestimate the gain.
Since the first generation of cellular networks was rolled out, priority has been to improve connectivity and capacity densely populated areas, such as urban centers, whereas rural areas received less attention. The lower subscriber density makes it difficult get a positive business case with current wireless technologies cost structures. Base stations are deployed more sparsely in typically shared by several operators thus not able provide high-performance connectivity, compared resulting...
This paper describes a Copper Plant Manager concept for DSL first mile, which effectively enables performance monitoring, fault interpretation and dynamic link management. copes with the nature complexity of underlying network presents unified solution controlling managing its resources. An implementation CPM embedded in Network Management System is described, together method proposed using it to allocate resources satisfy requirements resource- demanding multimedia services such as IPTV.
This work investigates a mechanism for alignment of the timing on which spatially distributed and cooperative radio units transmit in radio-frequency (RF) when served over packet-based fronthaul. It analyzes problem by considering imperfect clock synchronization packet delay variation that fronthaul packets are subject to. Following analysis, this paper proposes an implementation architecture RF transmission based synchronized triggering among centralized processing units. Throughout...
The new 3GPP New Radio standard (NR) has been designed with deployment flexibility in mind to enable high-rate mobile broadband services as well massive and ultra-low latency machine type communications for verticals. In this paper, we discuss the challenges potential solutions provide full surface coverage based on main-stream terrestrial cellular technology all use-cases. improving e.g. using 5G self-backhauling, resource sharing, protocol parameters are discussed. paper includes results...
This work proposes a compression method developed to transport radio signals over centralized access network using functional split in which the fronthaul transports frequency-domain samples. The proposed allows detecting subcarriers from an LTE/NR OFDM symbol are inactive avoid sending them fronthaul, hence decreasing required throughput and making it vary with usage. was evaluated different scenarios, results were analyzed terms of user equipment goodput traffic. simulations show...
In this paper the spectral features of impulse noise in DSL systems are mapped from waveform domain onto symbol domain, considering a QAM receiver. This work can be viewed as part full model for noise, which should include amplitude and aspects. Since available models generally waveform-based, kind mapping is justified when symbol-based simulations intended, order to avoid computational overhead due demodulating samples generated on domain. The analytical development such provided well some...
