... solution and MMSE equalizer cannot achieve better BER performance [18]). Other advanced equalizers, such as decision feedback equalizer and iterative equalizers can efficiently improve the performance ... comes from the MMSE equalizer, MAP decoder, and the order of iterations. For each iteration, the MMSE equalizer performs three FFT operations, whose complexity is O(P/2log 2 P)...

... therefore x ∗ satisfies the original optimization problem. In other words, if we solve the reformulated problem for some λ ≥ 0 and get back a configuration for which  i B i (x i ) is C, for that ... Lagrangian form can be used to transform multiple constraints into Lagrange multipliers, fast bisection searches for λ are optimal only if a single Lagrange multiplier is used. (Bisection...
