Method of specifying non-allowable pulse characteristics
First Claim
1. A method for generating codes indicating characteristics of pulses within a pulse train used by an impulse transmission system, comprising:
- defining a non-allowable region within a pulse characteristic value range layout; and
generating a code which does not permit code element values to map to pulse characteristic values residing in said non-allowable region.

Abstract
A code specifies characteristics of pulses transmitted and received by an impulse transmission system. The invention provides methods for defining non-allowable regions within pulse characteristic value range layouts enabling non-allowable regions to be considered when generating a code. Various approaches are used to define non-allowable regions based either on the pulse characteristic value range layout or on characteristic values of one or more other pulses. Various permutations accommodate differences between temporal and non-temporal pulse characteristics. Approaches address characteristic value layouts specifying fixed values and characteristic value layouts specifying non-fixed values.
When generating codes to describe pulses, defined non-allowable regions within pulse characteristic value layouts are considered so that code element values do not map to non-allowable pulse characteristic values.
