To enhance the capacity of a multiple input single output (MISO) system in wireless
communications, the most widely used channel coding technique is the space time block …

Studies on slotted ALOHA (S-ALOHA) systems have a long research history and been quite
mature in the literature. However, this thesis revisits S-ALOHA systems by considering …

This paper proposes a new uplink scheduling algorithm that can increase the uplink VoIP
user capacity for ertPS scheduling in 802.16 e networks. This algorithm solves the problems …

Thanks to silence suppression, the VoIP capacity can be improved. When the voice users
are listening or thinking, the VoIP system does not need to allocate resources to them …

This paper proposes an efficient uplink scheduling algorithm that can perfectly support
various VoIP CODECs with VAD/DTX/CNG in M-WiMAX considering the variants of silence …

This paper proposes a flexible uplink scheduling algorithm that can perfectly support
Variable Multi-Rate Wide-Band (VMR-WB) VoIP services with multi-mode codec, solving the …

In this paper, traffic cost of VoIP under IEEE 802.16 e/m with adaptive multi-rate (AMR)
speech codec is estimated based on state transition chain of Engset model. Impact of …

The scheduling algorithm is one of the key technologies in LTE-Advanced system. In this
paper, a semi-persistent scheduling algorithm designed for the VoIP service in LTE …

Video surveillance applications have experienced an increase in demand over the last
decade. Surveillance systems can easily be found in places such as commercial offices …

VoIP services have been considered as one of the most important services in the next
generation wireless systems. VoIP service requires the same quality of service (QoS) …
