Abstract

VARIAS ESTACIONES EMISORAS (MS1-MS4) PUEDEN TRANSMITIR PAQUETES DE AJUSTE DE LLAMADA EN CANALES RACH Y PAQUETES DE INFORMACION DE USUARIO EN CANALES TCH A UNA ESTACION RECEPTORA (BTS) QUE ESTA PROVISTA DE UNA MATRIZ DE N SENSORES (A1-AN) Y CON UN RECEPTOR (RM) ADAPTADO PARA ADQUIRIR SIMULTANEAMENTE N-1 PAQUETES DE LAS ESTACIONES EMISORAS Y PARA DERIVAR DE LAS MISMAS N-1 SEÑALES DE SALIDA DE MATRIZ DISTINTAS (X1-XN-1). DURANTE UN CANAL RACH, LA IDENTIDAD DE LA ESTACION EMISORA (MS) ASI COMO LA DIRECCION DE LLEGADA ( ) Y LA POTENCIA ( ) DE SU SEÑAL SE ALMACENAN EN UNA BASE DE DATOS DE PARAMETROS (PDB) CON SU VECTOR DE PESO (W) CALCULADO CON LOS MISMOS (WVG) Y UN CANAL TCH UBICADO CON LOS MISMOS (CHC). TANTO DURANTE UN CANAL TACH O TCH, LOS VECTORES DE PESO DE UNA ESTACION EMISORA SON SUMINISTRADOS POR LA BASE DE DATOS Y SE APLICAN A MULTIPLICADORES (M1-MN-1) QUE PRODUCEN LAS N-1 SEÑALES DE SALIDA DE MATRIZ. EN CASO DE INTERFERENCIA ENTRE ESTACIONES EMISORAS QUE USAN EL MISMO CANAL TCH, SE DISPONE OTRO CANAL TCH HACIA EL CUAL SE REUBICAN LAS ESTACIONES INTERFERIDORAS Y LOS VECTORES DE PESO. LAS ESTACIONES TAMBIEN PUEDEN ENVIAR PAQUETES EN EL CANAL RACH PARA ACTUALIZAR SUS PARAMETROS Y DE ESTA FORMA LOS VECTORES DE PESO EN LA BASE DE DATOS. EL PRESENTE SISTEMA DE RADIO TELECOMUNICACIONES ES PARTICULARMENTE ADECUADO PARA EL "GLOBAL SYSTEM FOR MOBILE COMMUNICATIONS" PARA EUROPEO GSM EN EL QUE LAS ESTACIONES EMISORAS SON ESTACIONES MOVILES.
