In order to deliver mobile services, multimedia broadcast multicast services (MBMSs) over single frequency networks (MBSFNs) have been standardized for long term evolution (LTE) systems, where an MBSFN comprises a number of synchronized base stations (BSs) cooperatively multicasting MBMS streams. In this letter, we propose a two-phase power allocation algorithm for an MBSFN. The algorithm first decides...
This paper proposes a resource allocation algorithm for multicasting video streams to users with diverse screen sizes. In order to gain from multicasting, quality of the channel has to be sufficiently high for the all users, and probability that such channel happens become lower as the number of the users grows. Therefore, this paper considers orthogonal frequency division multiple access (OFDMA)...
This paper proposes resource allocation method for transmitting video streams intended to multiple users over time-varying wireless channel. Medium grain scalable video coding is employed to compress the video streams. The video coding method provides packets which can be dropped for bit rate adaptation at the cost of decoded video quality. This paper also employs adaptive modulation. It can provide...
This paper proposes multiuser orthogonal frequency division multiplexing system for compressed video packets. Normally, video coding technologies compress video contents by removing similarities inherent in the video contents, so that it causes dependencies among the packets. It eventually results in inequality in terms of influence on video distortion, so that unequal protection is required to achieve...
Orthogonal frequency division multiplexing provides frequency diversity gain when assuming frequency selective channel which happens in most cases of wireless mobile communications. The frequency diversity can be utilized by considering data which requires unequal protection. Video data coded by scalable video coding method is an example. The video coding method encodes a certain picture period termed...
