    摘要: Enhanced performance is realized in a wireless transmission arrangement that is subject to fading by employing a perspective that combines array signal processing with channel coding. Specifically, in accordance with our invention, antennas at the transmitter are partitioned into small groups, and individual space-time codes are used to transmit information from each group of antennas. At the receiver, an individual space-time code is decoded by a linear array processing technique that suppresses signals transmitted by other groups of antennas by treating them as interference.

    摘要: Certain embodiments of the present disclosure provide a method for switching radio frequency (RF) carriers that serve communication between a base station (BS) and a mobile station (MS). The switching of carriers can be viewed as a handoff procedure between two different RF carriers within the same BS. A simplified handoff procedure for switching of RF carriers can be applied when the MS switches its physical connection from a primary RF carrier to a secondary RF carrier, as well as in the case when the BS decides to move the MS from one primary RF carrier to another primary RF carrier.
