<{p}>Space diversity or antenna diversity employs two or more antennas <{u}>spaced apart by a significant fraction of the wavelength<{/u}> so as to achieve a higher probability of receiving a non-faded signal.<{/p}>

【单选题】
A placed sufficiently apart measured by the wavelength
B far enough to make the wavelength only a fraction of the spacing
C separated by a distance less than a wavelength but not too small
D divided by a few wavelengths

<{p}>In such a fiber rays traveling at larger angles with respect to the axis <{u}>have to traverse a longer path<{/u}> and hence take a longer time than those rays which propagate with smaller angles to the axis.<{/p}>

2

<{p}>By keeping the off state slightly below threshold, the delay between the applied electrical pulse and the resulting optical output pulse is minimized; <{u}>this delay must indeed not be more than the bit interval<{/u}> so that the optical pulse can accurately reproduce the input signal.<{/p}>

3

<{p}>Computations show <{u}>a reduction of 6dB in the EM field intensity with the distance doubled<{/u}>, and an increase of 3dB in the intensity with the transmitted power doubled. This result provides verification to the algorithm used.<{/p}>

4

<{p}>This is possible because stations that are physically far enough from each other can use the same carrier frequency (frequency reuse) with negligible mutual interference, except at some point in the middle <{u}>where the stations are received with comparable signal levels.<{/u}><{/p}>

Wireless services have been growing at a rate greater than 50% per year, with the current second-generation European digital systems (GSM) being expected to be filled to capacity by the early 2000s.

As long as 750Mbps lines are not likely to be a part of the telecommunication system generally accessible to the public in the near future, the latter strategy appears to be more feasible.

<{p}>While the subject of coding <{u}>often carries an air of secrecy<{/u}>, a more important motive in many modern coding systems is the improved efficiency in conveying information.<{/p}>

<{p}>Our reliance on computer technology <{u}>has left us vulnerable to attack<{/u}>, and the vulnerability creates difficult political dilemmas that must be dealt with should we wish to continue following the currents of the Third Wave.<{/p}>
