Abstract
A system and method for signal cross-correlation using adaptive polar quantization and polar multiplication is disclosed. The method includes receiving a first and second complex signal. The method includes computing a first quantized phase and a first quantized magnitude based on a first adaptive polar quantization of a sample of the first complex signal and computing a second quantized phase and a second quantized magnitude based on a second adaptive polar quantization of a sample of the second complex signal. The method includes computing a polar multiplication based on the first quantized phase, the first quantized magnitude, the second quantized phase, and the second quantized magnitude to generate a rotated quantized phase and a multiplied quantized magnitude; converting to component real and imaginary parts; and computing a sum using complex addition.
