Otherwise, the decoding process is iterated until the predetermined maximum iteration count is reached.
However, in the proposed method, when either the maximum iteration count is exhausted or all candidate solutions acquire the same fitness, the iterative computation stops.
The termination criterion may be selected by defining maximum iteration count or accuracy of solutions, etc.
When the maximum iteration count is set to 20, the throughput is 14.32 Mbps.
We estimated the throughput variation according to the changes in the operating clock speed and the maximum iteration count by the SNRs.
For each SNR value, we assessed the average number of iterations and the minimum number of iterations with the maximum iteration count set to 50.
Based on the observation that the maximum decoding iteration counts differ according to the SNR values, we obtained the set of operating frequencies and supply voltage levels for which the proposed decoder would operate to satisfy the throughput requirement of the CMMB standard.
The weighting factor is evaluated based on the equation as follow: u = u_{hbox{max} } - frac{{u_{hbox{max} } - u_{hbox{min} } }}{{N_{iter,hbox{maxx} } }} cdot N_{iter} (22 where u max and u min are maximum and minimum value of inertia weight respectively; N iter is iteration count; N iter,max is maximum number of iterations.
The inertia weight change in succeeding iteration is described as [11, 12]: w = w_{ hbox{max} } - frac{{w_{ hbox{max} } - w_{min} }}{itermax} times iter (5 where iter is the iteration count, itermax is the maximum number of iterations, and wmax and wmin, are the upper and lower limits of inertia weights, respectively.
Step 0: Initialization; Set (k = 0), (K = 50), center factor (sigma in left( {0,;1} right)), tolerance (xi_{1} = 10^{ - 6}), (xi_{2} = 10^{ - 4}), in which, (k) is the iteration count and its maximum respectively.
The proposed primal dual interior point algorithm can be summarized as follows: Step 0: Initialization; Set (k = 0), (K = 50), center factor (sigma in left( {0,;1} right)), tolerance (xi_{1} = 10^{ - 6}), (xi_{2} = 10^{ - 4}), in which, (k) is the iteration count and its maximum respectively.
