Signal Combining System for Constant Envelope Transmission of Information

摘要

A method and apparatus for producing a transmission of constant envelope on a carrier signal. All possible combinations of all component codes for phases for producing the transmission are defined. Desired component code powers and desired intercode phases between all pairs of component codes are also defined. Still further, a portion of variables of a search process to reduce a number of variables searched by the search process is defined. Even further, deltas and weight variations for standard differences in a Jacobian matrix for use in the search process are defined. Penalty factors to evaluate an objective function of the search process are also defined. The search process is performed.

1. A method for producing a transmission of constant envelope on a carrier signal comprises:
defining, using a signal combing system having a processor, all possible combinations of all component codes for phases for producing the transmission; defining component code powers and intercode phases between all pairs of component codes in the combinations of all component codes using a system of equations having a number of variables; defining a portion of variables of a search process to reduce the number of variables searched by the search process; performing the search process using a Jacobian matrix to determine values for the portion of the number of variables; defining the component codes using the values for the portion of the number of variables from the search process; and transmitting the signal using the component codes from a transmitter to a destination device.
