Minimum Bit Error Rate Assisted QPSK for Pre-FFT Beamforming in LTE OFDM Communication Systems

Waleed Salos, Mohamad Khdair, Mos'ab Ayyash.

In this paper, a diamond shape pilot arrangement for OFDM channel estimation is investigated. Such arrangement will decrease the number of pilots transmitted over the communication channel which in turn will increase data throughput while maintaining acceptable accuracy of the channel estimation, the adaptive antenna array (AAA) is combined with orthogonal frequency division multiplexing (OFDM) to combat the intersymbol interference (ISI) and the directional interferences. In this paper, The optimum beamformer weight set is obtained based on minimum bit error rate (MBER) criteria in diamond-type pilot-assisted in 3GPP long term evolution (LTE) OFDM systems under multipath fading channel. The simulation results show that the quadrature phase shift keying signaling based on MBER technique utilizes the antenna array elements more intelligently than the standard minimum mean square error (MMSE) technique.

Key words: MBER beamforming, OFDM systems, Pre-FFT, Diamond shape pilot, 3GPP, LTE.
