In recent years the quadratic program (QP) is applied for the blind signal detection of the time-varying OFDM systems. The minimum solution of the QP is obtained by means of exhaustive search in the vector space, which often involves large and nondeterministic complexity. In this paper, we derive some formulas describing the probability information about the received PSK-type signals. With these formulas,...
After pointing out the limitation of the traditional multifractal wavelet model (MWM), and analyzing multi-resolution characteristics of real video traffic, this paper proposes an adjustable scale coefficient MWM model. The improved MWM can adjust wavelet coefficients and multiplicative coefficients based on their distribution of the real network traffic, which can suit the real network characteristics...
In recent years the quadratic program (QP) is applied for the blind signal detection of the time-varying OFDM systems. The minimum solution of the QP could be obtained through the class of the sphere decoder (SD) algorithm, which is equivalent to the tree search approach. In this paper, we derive some formulas describing the probability information about the received signal. With these formulas, a...
