Linear-Programming Design of Data-Communication Pulses
Tolerant of Timing Jitter or Multipath
The amount of multipath spread or timing jitter that a
data-communication signal can tolerate depends on the
shape of the receive-filter output eye pattern around
the optimal sampling instant. Ideally, the height of
the eye opening would remain unchanged as the sampling
instant deviated from the optimum. If there is enough
excess bandwidth to permit the necessary design
control over the shape of the system pulse, a
practical system can be designed that is quite close
to this ideal. Such high-bandwidth systems might be
found in multipath-prone environments or in
"fallback" modes of high-speed systems, for example.
Here example designs demonstrate linear-programming
optimization strategies that use that bandwidth to
make the eye opening flatter near the optimal sampling
instant for an hybrid FIR/analog pulse-shaping system
subject to spectral-mask constraints.
