In this paper an encoder/decoder pair with memory is designed for fault detection (FD) over networks. The basic idea is to estimate the support of the difference between the process measurement and the estimated one. Then by applying quantization with a uniform quantizer a symbol representing the quantization cell is transmitted. Firstly the channel without packet loss and bit errors is considered...
Voice communication over a tandem connection of a wireline packet switched network and an IEEE 802.11 access point is studied when there are packet losses in the wired IP network and bit errors in the WLAN link. Limited retransmissions are allowed, and packet loss concealment is utilized. We consider several alternative scenarios, including tandem free operation with G.711 in both links, G.711 over...
