    Abstract: The present invention is a communication system and method having a base station for communication with multiple remote units. The system comprises a base station which utilizes a plurality of sets of frequencies for selectively communicating with remote units in a predefined coverage area. The coverage area is divided into N concentric regions, where each concentric region is assigned one of the plurality of frequency sets such that for any given concentric region a different frequency set is assigned than the frequency sets assigned to all other adjacent concentric regions. The base station includes a means for communicating data to a remote unit over the set of frequencies associated with the respective concentric region as the remote unit travels from one concentric region to another. The system also comprises at least one remote unit having means for communicating with the base station over the set of frequencies associated with the respective concentric region as the remote unit travels from one concentric region to another.

    Abstract: A method employed by a remote unit wherein a plurality of channels are received as a received signal. Each channel is associated with a code. For each of the plurality of channels, others of the plurality of channels are subtracted from the received signal and a result of that subtracting is despread as data for that channel.

    Abstract: A spread spectrum remote unit receives a spread spectrum signal. The spread spectrum signal includes a reference signal and a message signal. The message signal has message data. The reference signal is detected within the received combined spread spectrum signal. The message data of the message signal is recovered using the reference signal. A spread spectrum remote unit produces a message signal having message data. A reference signal is produced. The references signal is used in recovering the message data from a combined spread spectrum signal. The reference signal and the message signal is combined as a combined signal. The combined signal is transmitted as the combined spread spectrum signal.

    Abstract: A remote unit transmits data by Frequency hopping over a set of frequencies to a base station. A plurality of antennas at the base station receives the transmitted frequency hopped data. An optimal combining of each antenna's received hopped data for a particular frequency is determined. Data is selectively transmitted using the plurality of antennas from the base station to the remote unit over the particular frequency. The selectively transmitting is selected using the optimal combining.
