Abstract: A method for introducing hysteresis into a hard handoff decision in code division multiple access (CDMA) communications following an initial hard handoff is provided. The method introduces hysteresis when it is determined that the communicating mobile station system clock is slewing. The slewing determination follows from a calculation of the rate of change in the round trip delay (RTD) in communications with the mobile station. A calculated RTD rate of change is compared with a RTD slewing threshold, where the RTD threshold is the assumed slew rate of the mobile station. Hard handoffs are suspended as long as the calculated RTD rate of change exceeds the RTD slewing threshold. A system and apparatus to implement the above-described method are also provided.

Abstract: The software reconfigurable transmission line apparatus uses a multi layer printed circuit board on which is deposited a plurality of signal conductors and associated ground plane conductors. The signal conductors and ground plane conductors are oriented in a parallel juxtaposed configuration such that they implement a two wire shielded transmission line. Switching devices located at either end of each of these conductors are operable under software control to reconfigure the connection of these conductors to their associated terminals to implement two wire floating or coax transmission lines.
