- Abstract
- This paper proposes simple structure of a receiver for blind communication system in impulsive noise environment, because the noise causes significant performance degradation when impulse component occurs. In conventional blind receiver, an equalization algorithm to overcome impact of the faded channel and a demodulator exist. However, the conventional receiver provides poor performance when the received symbols affected by impulsive noise are detected, for the impulse is much more dominant than the signal. Especially, it is difficult to demodulate the transmitted symbols interfered with the noise in low signal power, because most of research outcomes focus on reducing the effect of fading channel. Thus, this structure is composed of non-linearity, which blocks out or clips the received samples larger than threshold to be optimized, and equalization algorithm with binary search scheme that the computation amount is exponentially decreased. To allow a practical design of the proposed structure, simple calculation of threshold for non-linearity is also discussed in this paper. Simulation results illustrate that performance of the proposed structure in this paper is improved in low SNR.
