Abstract  Abstract

A WIRELESS COMMUNICATIONS SYSTEM COMBINES THE TEMPORARY AND SPACE DIVERSITY TO REDUCE FADING AND SIMPLIFY THE RECEIVERS DESIGN. IN PARTICULAR, A PACKAGE THAT TRANSPORTS DIGITAL TELEPHONE TRAFFIC, IS TRANSMITTED IN THREE DIFFERENT TIMES FROM THREE DIFFERENT ANTENNAS. THE MOBILE SUBSCRIBER RECEIVER RECEIVES THE SAME PACKAGE IN THREE DIFFERENT TIMES FROM THREE DIFFERENT ANTENNAS, AND USES THE BEST DATA PACKAGE OR A COMBINATION OF THE DATA PACKAGES TO REDUCE THE EFFECTS OF DISADVANTAGE. A TRANSFER STATION RECEIVES A MULTIPLEX MULTIPLEX ACCESS SIGNAL (TDMA) BY TIME DIVISION FROM A BASE STATION THAT CARRIES THE TRAFFIC OF TELEPHONE DATA PACKAGES TO FORM THREE DATA PACKS REPEATED TO DIVERSITY LOCATIONS OF DIVERSITY. THE TRANSFER STATION ALSO MODULES A MULTIPLE ACCESS SYSTEM (CDMA) BY CODE DIVISION USING A TDMA SIGNAL THAT LINKS THE MOBILE SUBSCRIBER TO THE TRANSFER STATION. EACH DATA PACK RECEIVED AT THE TRANSFER STATION AT THE TRANSFER STATION DIFFERENT FROM THE MOBILE SUBSCRIBER STATION IN A CDMA LINK. IN AN EMBODIMENT, EACH TRANSFER STATION INCLUDES THE THREE ANTENNAS IN SPACE DIVERSITY. IN A SECOND EMBODIMENT, THREE TRANSFER STATIONS, EACH ONE IS USED WITH AN ANTENNA OF SPACE DIVERSITY. MULTIPLEX SIGNS BY CODE DIVISION AND TIME DIVISION TRANSMITTED FROM ANTENNAS IN SPACE DIVERSITY SUPPLIES THE CAPACITY FOR THE SUBSCRIBER LOCATION THAT USES THE SAME COMMUNICATION SIGNS THAT ARE USED BY THE TELEPHONE DATA COMMUNICATION. SPECIFICALLY, THE RECEIVER OF THE SUBSCRIBER STATION USES THE ABSOLUTE AND RELATIVE TIME OF ARRIVAL OF THE THREE DATA PACKAGES REPEATED TO DETERMINE THE RESPECTIVE DISTANCE OF THE MOBILE SUBSCRIBER STATION TO THE THREE TRANSMITTER ANTENNAS. AS THE TRANSMITTER ANTENNAS ARE IN FIXED LOCALIZATIONS, THE RECEIVERS LOCATION IS DETERMINED.
