Abstract

05094-1 ZOO62_7K5 42 WO 6@0'C TRANSMIT SPATIAL DIVERSITY FOR CELLULAR SINGLE FREQUENCY NETWORKS ABSTRACT MULLIPLE-111 MULTIPLE-OUT (MIN10) TECHNIQUES ARE USED TO INCIEASE SPECTRAL EFFICIENCY OF A CELLULAI SINGLE FIECLUENCY NETWORK. IN SOME EMBODINICILLS VVITH SILL-IC TRANSMIT ANTENNA PEI CELL, MULTIPLE DATA STREAMS ARE TRANSMITTED FROM MULTIPLE CELLS, ONE DATA STREAM PER SET OF TRANSNUT AMENNAC. THE INAPPING- OF SIRE@IRNS TO ANTENNA SETS IS FICRI-NINTED IN TIME. IN THIS WAY, USER EQUIPMENT DEVICES (UES) AT CELL ED-ES BENEFIT FROM 1N/10@ AND UES NEAI CELL CENTERS BENEFIT FROM HIGH CARRIER-TO-INTERFEIENCE (C/1) RATIO OF THE SIGNAL. IN SOME EMBODIMENTS, EACH STREAM IS CONCURRENTLY TRANSMITTED OIL BASE LAYER OF A HIERARCHICALLY MODUK](CD SIGNAL FROM ONE SET, AND ON ENHANCEMENT LAYER OF A HIERARCHICALLY MODULATED SIGNAL FROM ANOTHER SET. THE MAPPING OF SETS TO STREAMS IS PERMILLED IN TIME. THE (JES AT CELL EDGES BENEFIT FROM MIMO, AND THE UES I1CAR CELL CENTERS HENEFIT FROM THE HIAH C/1 TO DECODE BOTH STFCAL11S FROM THE BASE AND ENHANCEMENT LAVERS. I
