Abstract: Techniques to quickly adjust an SIR target toward a final value needed to achieve a specified target BLER for a data transmission. The outer loop may be implemented with multiple modes. The SIR target may be maintained fixed in a hold mode, adjusted in large down steps to speed up convergence in an acquisition mode, and adjusted by a small down step and a large up step for good and erased blocks, respectively, in a tracking mode. Various schemes may be used to adjust the SIR target by larger down steps in the acquisition mode. These schemes may be used even if data is transmitted intermittently, the target BLER is set to a low value, and/or one or multiple transport channels are used for data transmission. The SIR target may be boosted by a particular amount upon transitioning from the acquisition mode to the tracking mode.

Abstract: Noise gain control within a communications receiver allows optimization of the receiver design without regard to the predetermined Automatic Gain Control set point. A noise gain controller is provided a copy of the received signal following AGC stages. A noise estimator determines the level of noise within the received signal and couples the noise level estimate to a noise gain discriminator that processes the noise level estimate to produce a gain correction factor. The gain correction factor is filtered and accumulated. The accumulated gain correction factor is used to scale the received signal. Subsequent receiver stages process the scaled received signal.
