However, the frequency error, which depends on variations in temperature, increases the receiver bandwidth, and thus both the receiver sensitivity and selectivity are degraded, even though the automatic frequency control (AFC) function is active.
where [BW.sub.transmitter] and [BW.sub.receiver] are the interferer and receiver bandwidths, respectively.
where [E.sub.n] is in dB (above 1 [mu]V/m), frequency f is expressed in MHz, and the receiver bandwidth B - in dB (where B is in dB-Hz).
Keeping the altimetric beat frequency constant allows a narrowing of the receiver bandwidth and a corresponding improvement of the receiver sensitivity (improving the signal/noise ratio).
* Choosing a waveform that compresses the information into a smaller bandwidth allows the receiver bandwidth (B) to be reduced and therefore reduces the required receiver input power.
In the case of the UWB receiver, the performance improves (minimum detectable signal (units: watts * [sec.sup.2] or volts * sec) is less) as the receiver bandwidth increases because more signal transient energy is captured, and because of the assumption that the signal bandwidth is greater than the noise bandwidth.
In the discussion of EW search strategies (January to April 1998), it was noted that increased receiver bandwidth allowed increased probability of intercept - with a wide-open receiver providing the ultimate in frequency-versus-time performance.
This phenomenon is known as pulse desensitization, and the product of pulse width and receiver bandwidth is known as the desensitization factor.
In the August 1995 "EW 101," there is a formula for the amount of noise power (kTB) in any given receiver bandwidth. In a typical application, the amount of signal power from a DS spread-spectrum signal will be less than this amount of noise power.
(We take this to mean that this amount of spectrum must be within the receiver bandwidth in order for us to detect the presence of the signal.) The search receiver bandwith has units of Hz, kHz or MHz.
The receiver bandwidth is greater than 250 MHz and supports greater than 155 Mbps data rates at mm-wave frequencies without complex multipath suppression schemes.[4] LO tuning is better than 1 GHz to allow for microcell isolation through frequency re-use schemes.
It is, of course, assumed that the receiver bandwidth is ideally sized and tuned to the desired signal.
