Cellular wireless communication standards, such as LTE-A, are primarily developed for the content distribution of user specific data via unicast transmissions. Long Term Evolution Advanced (LTE-A) describes the latest evolution of the mobile network standard of the 3rd Generation Partnership Project (3GPP). Research within this emerging domain are described.ĪBSTRACT. This purpose, the research challenges that may encourage further In the QoE enhancement in future broadcasting services. Survey to better understand the role that mulsemedia could play Paper aims at providing the broadcasting community with a Results are summarized based on subjective qualityĪssessments for audio-visual sequences which are enriched withĮffects, such as ambient light, wind and vibration effects. The researches conducted in the area QoE for mulsemedia This paper provides an updated overview of The impact of mulsemedia on the perceived user's quality ofĮxperience (QoE). In this research domain, a key issue is the measure of (mulsemedia) aimed at increasing user's experience through theįive sense representation (i.e., taste, sight, touch, smell, and Realistic media contents are media with multiple sensorial effects Services is to provide realistic media contents to the users. One of the goals of next generation broadcasting Experimental results show that the spectral efficiency is increased up to about 98.2% for the digital terrestrial multimedia broadcasting (DTMB) and digital video broadcasting (DVB) systems.ĪBSTRACT. According to the two diversity gains, the bit-error-rate performance of the proposed scheme gets lower for increasing the Doppler spread. In the doubly selective fading channel, the Doppler and multipath diversity gains are retrieved from the oversampled signal. Furthermore, narrow frequency guard intervals are reserved between subbands by filtering to resist the inter-subband interference, which can maximize the spectrum utilization. Through subtly designing filters, the out-of-band emission of the signal is significantly depressed. Meanwhile, a multistage interpolator architecture is applied to each subband, resulting in a reduced computation complexity. In the E-OFDM system, the divided subbands realize parallel transmission in the time domain, which decreases the sampling rate. In this paper, an enhanced OFDM (E-OFDM) scheme, using uniform subband division, is proposed to improve the spectral efficiency.
