Abstract
A method and apparatus for generating a frame quality indication of a frame of a received turbo encoded wireless signal is provided. A turbo decoder is used to decode a demodulated frame and provide a decoded frame. A turbo encoder is used to encode the decoded frame to provide a re-encoded frame. A modulator modulates the re-encoded frame. The frame quality is assessed based on a degree of correlation between the demodulated frame and the re-encoded modulated frame. The advantages include a less complex receiver due to reduced computational load, and potentially greater payload capacity in frames due to elimination of Yamamoto bits.
