Bit rate maximization loading algorithm with mean BER-constraint for linear precoded OFDM

Abstract—The resource allocation problem to maximize the bit rate of a linear precoded orthogonal frequency division mul- tiplexing (LP-OFDM) system is considered taking into

The definition of these two classes is useful for UWB systems, where multimedia or real-time applications (video recording, A/V conferencing, etc) should have

It can be observed that the proposed allocations are robust against the estimation noise and provide sustainable BER performance as compared to iterative OFDM allocation, which does

In such a scenario, users can decide their power allocation based on three possible Channel State Information (CSI) levels, which are called complete, partial and statistical..

In this paper, we investigate the effective exponential signal to interference and noise ratio method (EESM) in the MIMO-OFDM systems to predict the BER at the output of

The proposed pragmatic solution is the discrete bit loading algorithm, where for a given target bit rate and a given block length, L, we find the optimal number of useful

To increase the bit rate of this LCG method, the LP-OFDM bit loading in single user context, is applied on the equivalent channel and this method will be considered as linear

We consider only the bit rate offered by LBCG method which gives the best results. 3 shows the comparison of multicast bit rates for all couples of channel classes. The gaps among
