Great subject, really engaging and well taught, probably one of the best in the degree! I can honestly say I learnt many new, interesting things, both technical and about 'real world' comms systems. Also the way the assessment is structured means you're rewarded more for hard work than exam performance under limited time pressure. A H1 is very doable if you keep up with the content, had a decent grasp on the prerequisites (S&S, PARM) and have decent programming skills
