摘要： Base stations (101, 102) utilize a spreading code that is dependent upon whether the particular base station (101) is operating in a synchronized, or an unsynchronized mode. Unsynchronized base stations (102) within the communication system (100) utilize a long code unique to the particular base station (102), and base stations (101) operating in a synchronized mode utilize a time shifted version of the same long code. To reduce the search time for remote units (113) within the communication system (100), a group identification code (GIC) (305) is broadcast during a time period that the long code is masked. The GIC (305) indicates a (spreading code) long code group to which the long code of each base station belongs. Additionally, each base station (101, 102) within the communication system (100) determines its synchronization status and utilizes a particular GIC (305) and long code based on the base station's synchronization status.

摘要： A simulator/controller (113) performs real-time simulation for system control in a code-division multiple access (CDMA) wireless communication system (100). The simulator/controller (113) simulates the effects of interfering AMPS wireless communication systems which coexist with CDMA wireless communication systems and also aids in the placement of new CDMA base-stations in the presence of existing AMPS base-stations. When system parameters are input to the simulator/controller (113), real-time simulation of the CDMA wireless communication system (100) predicts potential problem areas of the CDMA wireless communication system (100) and controls the CDMA wireless communication system (100) to avoid the problems before they occur.

摘要： Providing communications service to a coverage hole (22) in a DS-CDMA cellular communication system (50) involves an OMC (52) determining the transmitters (134-144) in adjacent cells (122-132) to the coverage hole (22). The OMC (52) places each of the transmitters (134-144) in the adjacent cells (122-132) in a power on demand mode (92). The OMC (52) then selects at least one, but less than all of the transmitters (134-144) to increase power to a pilot channel. The selected transmitter(s) is chosen base on one or more of the following factors, the transmitter's level of unused power, the interference level at the transmitter and the position of the transmitter.

摘要： There is provided a method of rapid Received Signal Strength Indication (RSSI) of a time-dispersed signal having echoes (where the time dispersal represents a significant fraction or more of the transmitted symbol interval). It comprises a sliding correlation of a received signal against a known sequence or via channel sounding to obtain the time-dispersal function of the communications channel upon which the signal is transmitted and a summation of the squares of the quadrature components of the energies at relative maxima of the correlations (correlation peaks determined with reference to a threshold level) to integrate the energy defined by the correlation function to determine the energy present among the time-dispersed echoes utilizing the time-dispersal function. Thus, the energy present in the time-dispersed echoes is related to the received signal strength, the RSSI comprises a scalar of the energy present and the scalar comprises a function of the receiver's gain, RSSI determinations during any given interval are less dependent upon the ambulatory velocity of the receiver, and RSSI determinations of equivalent accuracy are obtained more rapidly or more accurate RSSI determinations are obtained per unit time.
