    摘要: A communication system including a first station having at least two first narrow beam antennas and a second station having at least two second narrow beam antennas. The first and second stations establish a first communication path for wireless communication via a pair of first and second narrow beam antennas. When communication via the first communication path is disturbed by obstacles, the first and second stations automatically establish at least one alternative communication path, which is spatially different from the first communication path, for wireless communication using the at least two first narrow beam antennas and the at least two second narrow beam antennas.

    摘要: Wireless communication systems are provided with an adaptive subcarrier loading function for a mobile receiver in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM) that can advantageously be applied to predict the channel transfer function of a multipath propagation channel being severely impaired by frequency-selective fading and an extremely time-variant behavior by detecting the position and/or movement of zero points of the transfer function, thereby reducing the probability of incorrect assignment of the modulation scheme for each subcarrier caused by mobile terminals moving at high velocity. The zero points of the estimated channel transfer function are determined by detecting the position of deep notches on the associated amplitude response of the measured channel transfer function caused by frequency-selective fading whose depths are larger than a predefined threshold.

    摘要: A demodulating apparatus that can reduce power consumption significantly compare to conventional cellular phones without the reception quality being degraded. Delay profile measuring is provided in which the delay profile (S41) of the baseband signal is measured while changing the measuring time for measuring the delay profile of the baseband signal, so that the measuring time can be held down to a minimum while avoiding the degradation of the reception power level. Therefore, power consumption can be significantly reduced compared to conventional cellular phones without reception quality being degraded.
