Abstract :
In this paper, a novel video streaming technique is proposed for the recently standardized IEEE802.16m system also known as the Wireless MAN-Advanced or WIMAX2 system. The antenna mode considered is single user spatially multiplexed (SUSM) transmission suitable for video streaming. In previous works, the linear signal detection method was used in order to achieve unequal error protection (UEP). In this paper, it is shown that a joint signal detection method can also be used to achieve UEP. Computer simulations demonstrate improved performance using the proposed method. In the simulations, H.264/AVC compressed video is used, and the PHY layer procedures such as resource unit allocation, convolutional turbo code (CTC), pilot tone insertion, and pre-coding are implemented in strict accordance with the IEEE 802.16m standard.
