Abstract
The delivery of digital multimedia data over wireless networks enables manY useful consumer applications such as home entertainment. However, there are many performance-related issues associated with the delivery of time-sensitive multimedia content over current wireless communication systems such as those using the IEEE 802.11 standards. Among the most significant issues are the high error rates, because of the media characteristics, and signal attenuation with distance. In this paper, we present a robust digital baseband processor using hybrid channel estimation for wireless home audio-video receivers operating on an IEEE 802.11g wireless local area network (WLAN). The proposed hybrid channel estimation is a combined decision-directed and pilot-assisted method for perfect channel state information (CSI). Experimental results show that the proposed method increases system performance by about 3 dB over the least squares (LS) scheme at 100-ns root mean square (RMS) delay.
