investigated in case of excluding the cross-pol Pre-RAKEs in the base station. The paper discusses the effect of the polarization diversity characteristics as well as the impact of the imbalance in the co-polarized power intensities on the BER performance. For slowly-varying channels, an assessment for the system performance will be investigated under… (More)
across the three dimensions with four frequency diversity branches, the proposed code has a four-wise maximum likelihood decoding. The system performance will be investigated under different delay spread of the channel. In addition, a performance comparison for different FFT size will be presented.
—This paper presents a novel quad-band power divider with equal power division ratio. The proposed power divider is realized using two cascaded sections of dual-band transformers based on coupled microstrip lines. Limitations of using dual-band quarter-wavelength transformers based on coupled lines are studied through parametric analysis to obtain useful… (More)
request, provided it is not made publicly available until 12 months after publication. Abstract In this paper, an advanced closed loop Polarized Multiple-Input Multiple-Output Pre-RAKE Combined Transmit Diversity " Pol MIMO Pre-RAKE CTD " system is proposed for the downlink. The proposed system is designed and analyzed in frequency division duplex mode. The… (More)
