## Simulcast signal behavior at the receiver

[latexpage] In my previous post on simulcast in paging, I mainly took a high level view of the system overall. In this post, I’m going to drill in a bit deeper at the receiver. To start simply, let’s assume we’re dealing with a relatively low data rate binary FSK scheme, like POCSAG at 512 or 1200 bit/s. In this case, the bit time is the symbol time, something like 1 to 2ms or so. Considering the speed of radio signals, at $300 \times 10^{6 }m\cdot s^{-1}$ the “length of a bit” will be around 150 to 300km. What this means is that radio signals will have every...
