Criteria for Minimum Bit Error Rate
نویسنده
چکیده
The stability behaviour of the iterative decoding (ID) of Turbo-Codes and its innuence on the overall performance are discussed. Several criteria to characterize the ID are proposed and the most reliable ones are determined. These criteria are used to partition the transnitted blocks into stable and unstable ones. For unstable blocks the decoding step is determined which most likely produces a low number of decoding errors. These operations allow to lower the bit error rate (BER) signiicantly and to detect the erroneous blocks with high probability. Simulations show an improvement in BER by factor 10 and more.

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...
متن کاملMinimum Ber Diagonal Precoder for Mimo Systems
We report on a simplified representation of Multi-Input Multi-Output (MIMO) systems and propose a Minimum Bit Error Rate (MBER) diagonal precoder. Assuming that channel information can be available at the transmitter, we show that the proposed representation decouples the MIMO channel into parallel subchannels, which greatly facilitates and speeds up further processing. Using traditional criter...
متن کاملMinimum Bit Error Rate Pre-FFT Beamforming for OFDM Communication Systems
In broadband wireless communication, the adaptive antenna array (AAA) is combined with orthogonal frequency division multiplexing (OFDM) to combat the inter-symbol interference (ISI) and the directional interferences. One of the two main techniques which are used in OFDM systems is called Pre-FFT, where an optimum beamformer weight set is obtained in time domain before Fast Fourier Transform (P...
متن کاملSpace-time decision feedback equalisation using a minimum bit error rate design for single-input multiple-output channels
This contribution proposes a minimum bit error rate (MBER) decision feedback equaliser (DFE) designed for single-input multiple-output (SIMO) systems employing a quadrature phase shift keying (QPSK) modulation scheme. It is shown that this MBER design is superior over the standard minimum mean square error DFE in the SIMO scenario considered, in terms of the achievable system bit error rate. A ...
متن کاملA Minimum Approximate-BER Beamforming Approach for PSK Modulated Wireless Systems
A beamforming algorithm is introduced based on the general objective function that approximates the bit error rate for the wireless systems with binary phase shift keying and quadrature phase shift keying modulation schemes. The proposed minimum approximate bit error rate (ABER) beamforming approach does not rely on the Gaussian assumption of the channel noise. Therefore, this approach is also ...
