Spectral Efficiency Enhancement using Hybrid Pre-Coder Based Spectrum Handover Mechanism

نویسندگان

چکیده

The use of Millimeter-wave (mm-Wave) has recently immensely enhanced in various communication applications due to massive technological developments wireless communications. Furthermore, mm-Wave consists a high bandwidth spectrum that can handle large demands data transmission and internet services. However, interference is observed previous research at the time handover from secondary (unlicensed) users primary (licensed) users. Thus, reduction by achieving spectral efficiency an easy handoff process with minimum delay important area. Therefore, Hybrid Pre-coder Design based Spectrum Handoff (HPDSH) Algorithm proposed this article increase Cognitive Radio Networks(CRNs) access systems meet rate current cellular networks. Moreover, HPDSH presented enhance algorithm utilized take decisions select backup channels. Here, different scenarios parameters are considered evaluate performance terms Signal Noise (SNR) ratio. compared against precoding methods like OMP SIC methods.

Offset-QAM based coherent WDM for spectral efficiency enhancement.

Optically multiplexed multi-carrier systems with channel spacing reduced to the symbol rate per carrier are highly susceptible to inter-channel crosstalk, which places stringent requirements for the specifications of system components and hinders the use of high-level formats. In this paper, we investigate the performance benefits of using offset 4-, 16-, and 64-quadrature amplitude modulation ...

Spectral efficiency of spectrum-pooling systems

In this contribution, we investigate the idea of using cognitive radio to reuse locally unused spectrum to increase the total system capacity. We consider a multiband/wideband system in which the primary and cognitive users wish to communicate to different receivers, subject to mutual interference and assume that each user knows only his channel and the unused spectrum through adequate sensing....

Hybrid Energy Supply based Energy Efficiency and Spectral Efficiency Tradeoff for Green Cellular System

The tradeoff between energy efficiency (EE) and spectral efficiency (SE) under the smart grid with joint energy harvesting and grid power supply is considered. The price factor in economics is used to propose the economic EE and SE. Then a new EE-SE tradeoff metric called the EE-SE adaptive tradeoff (ESAT) is built under the fluctuating harvesting energy. Furthermore, the offline optimization p...
