Patent ID: 8654907

Claim:
A broadcast receiver with improved response to long and short term fading which comprises: a processor configured to receive a data signal which is assessed with respect to a decision metric derived upon utilising the probability density function of a Suzuki distribution in a closed form: p a l ⁡ ( a l ) = ( 5 2 ) 1 8 ⁢ σ 2 ⁢ a 1 ⁢ ⅇ - μ 2 2 ⁢ σ 2 σ ⁢ 2 ⁢ π ⁢ Γ ⁡ ( 1 - 1 8 ⁢ σ 2 - μ 2 ⁢ σ 2 ) ⁢ ( - 1 8 ⁢ σ 2 - a l 2 2 ) - 1 + 1 8 ⁢ σ 2 + μ 2 ⁢ σ 2 where σ and μ denote the variance and mean value respectively of the Lognormal distribution, in order to take into account potential impairment of the said data signal.
