SISTEMA DE ANTENAS,ESTACAO DE BASE,SISTEMA DE COMUNICACOES LOCAIS E PROCESSO PARA CRIAR PROPAGACOES DE MULTIPLOS TRAJETOS DE SINAIS CDMA TRANSMITIDOS

摘要

A code division multiple access (CDMA) communication system in which cellular techniques are utilized in a wireless Private Branch Exchange (PBX) environment. A microcellular arrangement is defined in which a base station communicates user information signals using CDMA communication signals with subscriber terminals. A distributed antenna system is utilized in the system to provide multipath signals which facilitate signal diversity for enhanced system performance.
