1. A method for canceling interference in a radio signal in a wireless communications network, comprising:
- detecting, demodulating and decoding all of a plurality of interfering signals contained in the radio signal;
regenerating all of the interfering signals from the detected, demodulated and decoded signals; and
subtracting all of the regenerated interfering signals from the radio signal to recover a desired signal.

Abstract
A method cancels interference in a radio signal received in a receiver of a wireless communications network, such as a cellular telephone network. The interfering signals are serially detected, demodulated and decoded. Each of the decoded signals is then regenerated into its analog form and subtracted from the radio signal until a desired signal is recovered.
