Abstract

Fixed wireless access channels in the 5 GHz band have been measured with eight-element uniform linear antenna arrays at both ends, thus providing an 8/spl times/8 configuration. The measurements were performed at three different locations in downtown Toronto. The application of the time reversal (TR) technique in a multiple-input-single-output (MISO) configuration can reduce the delay spread of the channel impulse response by a factor of 2-3, depending on the power allocation scheme.
