“…The EVM curves reveal that, as expected, the broader the filter bandwidth is, the wider the allowed detuning is. However, the shape of the EVM curves is sensibly different to the case of single carrier modulation reported in Aldaya et al (2013a): in contrast to a sharp valley in which the EVM increases relatively fast as detuning does, in our case a broad plateau is present. This behaviour can be explained by the intrinsic robustness of OFDM signals to frequency selectivity.…”

The use of communication networks relying on millimeter-wave (mm-wave) wireless links promises a great capacity enhancement as well as improved security. However, given the high-directivity of mm-wave links, coverage requirements are difficult to meet unless the network is assisted by an infrastructure. Given its low-cost, powerefficiency, and high capacity, radio over fiber has emerged as a strong candidate for the implementation of such infrastructure. Among the different generation techniques, photonic heterodyning has attracted considerable attention due to its capacity to generate radio frequency (RF) signals in the entire microwave/mm-wave range without requiring broadband electro-optical modulator. However, the RF signals generated using these techniques suffer from significant phase noise, a major impairment that degrades the system performance. In this paper we study two approaches to overcome this limitation: (1) the use of optical sideband injection locking (OSBIL) to generate tones with highly correlated phase noise and (2) heterodyning independent lasers in combination with a mobile terminal (MT) that is insensitive to the phase of the RF signal. A qualitative comparison between the two techniques in terms of MT sensitivity to the RF phase noise, the power sensitivity, and base station power efficiency leads to the conclusion that OSBIL is more & Ivan Aldaya

“…Currently, 3GPP LTE-Advanced and IEEE 802.16 m are standardizing the self-organizing network concept for IMTAdvanced femtocell networks as well [3][4][5][6][7]. Moreover, considering the volume of traffic that is expected in the future years, the convergence of optic fiber backhauls to radio over fiber backhauls is quite promising in the case of heterogeneous networks [8].…”

The next generation heterogeneous networks are expected to offer higher data-rate and better QoS to the customers by leveraging smaller cells like femtocells and making use of orthogonal frequency division multiple access. However, uncoordinated dense deployment of femtocells in macrocell network pose unique challenges involving cross-tier interference and resource management which results in significant degradation of the system performance. As part of addressing these challenges for the successful integration of both technologies, this paper proposes the deployment of a self-organizing femtocell network that employs an opportunistic smart frequency reuse technique -cross polarized complementary frequency allocation (CPCFA). It exploits the frequency and polarization diversity to mitigate interference in two-tier femtomacro networks. In this work, a strategy combining the adoption of reverse frequency allocation and orthogonal polarized transmission is analyzed as a potential solution for maximizing spectral efficiency and minimizing interference in the existing heterogeneous networks. Focus of the current work is on downlink transmission where the traffic is high and the deployment of femtocell is more beneficial. The results of analytic and simulation studies prove that CPCFA increases the scope for an easily implementable, remarkable opportunity in the context of twotier femto-macro network that can substantially increase the system capacity as well as cell coverage without additional network complexities.
