Evolution Analysis ofIterative LMMSE-APPDetection forCodedLinear System withCyclic Prefixes
Xiaojun Yuan, Qinghua Guo · 2007
This paperisconcerned withtheiterative detec- tionprinciples forcodedlinear systems withcyclic prefixes. We derive a matrix-form low-cost fastFourier transform (FFT)basediterative LMMSE-APPdetector andpropose an evolution technique fortheperformance evaluation ofthe proposed detector. Numerical results showa goodmatch between simulation andevolution prediction. Keywords-LMMSE-APP detection, Turboequalization, iterative detection, SNR-variance evolution.
