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： Technologies for optimizing frequency allocations in mobile communication systems can include a probabilistic model that can consider interference quality, coverage quality, frequency hop set length, service type, environment, and mobile radio speed. A frame erasure rate (FER) objective for call quality may be used as a key performance metric as FER performance can be closely related to voice quality. Mobile allocation list (MAL) length selection during the optimization can attempt to optimize the MAL length at the sector level. Choosing a MAL length per cell can provide an additional degree of freedom during the optimization process. The model can consider signal quality of neighbor cells in handover areas. The model can trade off co-channel and adjacent channel interference. Co-channel interference can be reduced at the expense of adjacent channel interference.

摘要： A transceiver for implementing an adaptive vector modulation method is disclosed. In response to a binary stream assembled into groups of bits forming symbol indices, a transmitter of the transceiver generates one or more complex values symbols that are normalized over channel coefficients associated with one or more propagation channels between one or more transmitter antennas and one or more receiver antennas. The transmitter controls a transmission of the complex values symbol(s) from the transmitter antenna(s) to a selected receiver antenna. The selection of the receiver antenna is based upon a metric proportional to the average injection power or a vector norm corresponding to each receiver antenna of the receiver antenna(s).
