Joint multipath-Doppler diversity in mobile wireless communications
We introduce a new approach for achieving diversity in spread-spectrum communications over fast-fading multipath channels. The RAKE receiver used in existing systems suffers from significant performance degradation due to the rapid channel variations encountered under fast fading. We show that the Doppler spread induced by temporal channel variations in fact provides another means for diversity...
متن کاملExploiting Doppler Diversity in Mobile Wireless Communications
Signal fading due to variations in channel characteristics is one of the major factors limiting the performance of modern mobile wireless communication systems. To overcome fading, various diversity techniques have been developed that eeectively transmit multiple copies of the signal over the channel. The state-of-the-art receiver used in code-division multiple access systems is the RAKE receiv...
متن کاملJoint multipath-Doppler diversity in fast fading channels
We present a new framework for code-division multiple access (CDMA) communication over fast fading mobile wireless channels. The performance of the RAKE receiver, which is at the heart of existing CDMA systems, degrades substantially under fast fading encountered in many mobile scenarios. Due to the time-varying nature of the fast fading channel, we employ joint time-frequency processing, which...
متن کاملJoint Scale-lag Diversity in Mobile Wideband Communications
We consider the effect of mobility on a wideband direct sequence spread spectrum (DSSS) communication system, and study a scale-lag Rake receiver capable of leveraging the diversity that results from mobility. A wideband signal has a large bandwidthto-center frequency ratio, such that the typical narrowband Doppler spread assumptions do not apply to mobile channels. Instead, we assume a more ge...
متن کاملEstimation of multipath parameters in wireless communications
In a parametric multipath propagation model, a source is received by an antenna array via a number of rays, each described by an arrival angle, a delay and a fading parameter. Unlike the fading, the angles and delays are stationary over long time intervals. This fact is exploited in a new subspace-based high-resolution method for simultaneous estimation of the angle/delay parameters from multip...
