The effect of pulse-noise jamming noncoherent RAKE receiver with convolutional coding in the presence of Ricean fading is analyzed. The effect of additive white Gaussian noise (AWGN) is also included in the analysis. The maximum-likelihood RAKE receiver for the combination of pulse noise and AWGN is derived. Pulse jamming usually has a significant effect when soft decision decoding is used, however, we show that the maximum-likelihood RAKE receiver effectively mitigates pulse noise jamming. Hard decision decoding reduces the effect of pulse noise jamming, however, the maximum-likelihood RAKE with soft decision decoding performs better than hard decision decoding in the presence of pulse-noise jamming.
