In addition to detection over the joint ISI and IN states we also focused on another scenario where trellis transitions are not trivial: detection for the ISI channel with AWGN with inaccurate knowledge of the channel memory at the receiver.

An underestimation of the memory largely degrades the performance of both BCJR and BCJRNet, especially in a slow-decaying channel.
