Abstract
A transmitter stores mappings of distinct values of an information signal to corresponding ones of distinct combinations of K chirps taken from M chirps that are different from each other, such that each of the distinct values is mapped to a corresponding one of the distinct combinations of K chirps. The transmitter receives a distinct value among the distinct values of the information signal. The transmitter selects, based on the mappings, a distinct combination of K chirps among the distinct combinations of K chirps that is mapped to the distinct value. The transmitter sums the K chirps of the distinct combination of K chirps to produce a symbol that represents the distinct value. The transmitter modulates the symbol to produce a modulated symbol, and transmits the modulated symbol. A receiver receives a modulated symbol that conveys a distinct value, and recovers the distinct value using stored mappings.
