TITLE:

Linear-Programming Design of Data-Communication Pulses Tolerant of Timing Jitter or Multipath

ABSTRACT:

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.
