Impact of User Spread on the Input Power Spread in DL Massive MIMO in Random LOS Channels
Paper i proceeding, 2020
Presented are the spread of the amplifier output power and the sum rate capacity loss of a narrowband massive MIMO antenna system in a Random-LOS channel due to cell-sector narrowing. Coupling effects between the array elements have been neglected. A large power spread of the output power of the amplifiers is observed when users are spread over narrow sectors and ZF-precoding is used. The capacity is considerably reduced for both MF- and ZF-precoding, especially for the latter.
