Field test results of space-time equalizers and delayed diversity transmission in central Tokyo area

چکیده
AbstractField test of space-time (ST) equalizers for combating inter-symbol interference (ISI) at base station, was conducted in microand macro-cell environments in central Tokyo area. Test results indicate that the ST equalizers provide significant better bit error rate (BER) than an array processor alone dose, due to both space and path diversity while suppressing long-delayed path. Furthermore, a delayed diversity transmission (DDT) in a small delay spread environment provides sufficient delay-spread and improves BER of the ST equalizer.

Dual-time-point FDG-PET/CT Imaging of Temporal Bone Chondroblastoma: A Report of Two Cases
Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...

متن کاملSymbol-by-symbol and trellis-based equalization with widely linear processing for space-time block-coded transmission over frequency-selective fading channels
In this paper, we develop receiver concepts for transmission with space–time block codes (STBC’s) over frequency–selective fading channels. The focus lies on Alamouti’s STBC, but the results may be generalized to related STBC’s. We show that a straightforward combination of conventional equalizers and a space–time block decoder is only possible if at least as many receive antennas as transmit a...

Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...
متن کاملCharacterization of $2times 2$ full diversity space-time codes and inequivalent full rank spaces
In wireless communication systems, space-time codes are applied to encode data when multiple antennas are used in the receiver and transmitter. The concept of diversity is very crucial in designing space-time codes. In this paper, using the equivalent definition of full diversity space-time codes, we first characterize all real and complex $2times 2$ rate one linear dispersion space-...
