Matching pursuits over a basis of separable Gabor functions has been demonstrated to outperform DCT methods for low bit rate video coding. This paper introduces an error resilient implementation of the matching pursuits algorithm, based on the error resilient positional code. Coded video is transmitted using the simulated HIPERLAN/1 air interface standard, which recommends ARQ as a means of overcoming channel errors. This may be unsuitable for real time and broadcast applications. Therefore, a modified HIPERLAN/1 receiver is proposed in this paper, which does not use ARQ to retransmit erroneous packets but instead passes them to the video decoder to exploit error resilience. This strategy provides an acceptable reconstruction quality for average bit error rates equal to 1 in 1000 and is superior to a standard compliant system in the absence of ARQ. This confirms that wireless LAN standards should support a transparent mode for video applications.
