We first present new closed-form expressions for optimal received Signal-to-Noise Ratio (SNR),which is expressed in polynomial form. These are used to analyze ergodic capacity,outage probability and Bit Error Rate (BER) of TAS/MRC systems. Numerical results are presented to validate the theoretical analysis.展开更多
随着5G时代的到来,各地5G基站的建设如火如荼,同时5G网络建设存在工程投资大、5G天线部署需要关注覆盖性能及部署周期等问题。文章针对在利旧基站建设过程中存在的天面空间受限、5G低挂高、铁塔风荷载受限等问题,对A+P(Combination of a...随着5G时代的到来,各地5G基站的建设如火如荼,同时5G网络建设存在工程投资大、5G天线部署需要关注覆盖性能及部署周期等问题。文章针对在利旧基站建设过程中存在的天面空间受限、5G低挂高、铁塔风荷载受限等问题,对A+P(Combination of active and passive antennas)一体化设备在中国电信和中国联通的5G基站建设中的使用方式提出一些建议,根据A+P设备在不同建设场景来进行工程建设、投资分析,说明A+P一体化设备的较高实用性。展开更多
