Wideband T-shaped cross-section monopole antenna fed sideward from a ground plate
Kyoichi Iigusa,Hiroshi Harada +1 more
TL;DR: In this paper, a rectangular monopole antenna fed sideward from a ground plate by modifying its cross-sectional shape was investigated, and it was found that the monopole under the ground plate can be shortened by making the cross-section T-shaped without significantly degrading the wideband impedance matching property.

Recepteur, procede de reception, et milieu d'enregistrement qui enregistre un programme pour recevoir des signaux de donnees
TL;DR: In this article, the caracteristiques du chemin de transmission estimees were used to estimate the signal recu and the caracters of the signal de donnees.
Patent
Data rate dependent control channel allocation
TL;DR: In this article, the use rate of the transmission buffer is used to decide how slots of a frame of an uplink channel are structured when a base station generates an FCM.

The evaluation of pilot symbol pattern in OFDM system from practical perspective
TL;DR: A set of pilot patten is proposed for a network operating in VHF/UHF band based on 802.16 WiMax design pattern and the effects of different pilot symbol insertion schemes on the error performance of OFDM-QPSK are evaluated.
Journal ArticleDOI
A Novel Method of Estimating the Signal-to-Interference Ratio for One-Cell-Frequency-Reuse OF/TDMA Systems
TL;DR: A novel SIR estimation method that uses a spread pulse-wave symbol and carrier interferometry and is modified by allocating a different spreading code to each cell to introduce multi-input multi-output systems.
