In addition, the ... 7]. Packet loss in wired networks is mainly the result of network congestion. SCTP congestion control must adjust the congestion window size. Conversely, packet loss in a wireless network...

Consequently, ... comprising a single tap FIR filter operating within each filterbank bin.
