Although the critical upper threshold of Catot/Caion ratio ≥2.5 was exceeded 10 times in seven different CVVHD runs, equalization of initial metabolic acidosis was possible without major disturbances of acid-base and electrolyte status.
However, the initial coefficients of equalizer tap weights are always neglected among improved equalization methods, which are also critical to the whole iterations and convergence rate.
Despite the encouraging equalization of the initial acidosis, citrate accumulation might in part be responsible for the metabolic acidosis after 72 hours because elevated citrate levels and an increased Catot/Caion ratio were observed in these runs.
In this paper, a typical channel estimation method, least square (LS) algorithm, is applied in adaptive equalization to obtain the initial tap weights of least mean square (LMS) algorithm.
However following the initial pass, the SISO MMSE equalizer computes a soft estimate of the IBI that is to be used in the soft IBI and ISI cancellation prior to the equalization.
In [29], we proposed an enhanced equalization method and we utilize it for the initial processing of the received CL-LINC-OFDM signal.
Specifically, the article investigates the improvements in uplink physical layer performance achieved by adding an initial antenna combining step in the DAS system before conventional combining and equalization at the BTS.
In this paper, a novel equalization algorithm is proposed which utilize channel estimation to define the initial values of receiver equalizer taps.
This equalization has to occur at a much slower rate than the initial charging in order to avoid damaging the battery and to prevent fire or explosion.
