This deliverable presents channel measurement results for the scenarios Open exhibition and Crowded auditiorium. The measurement procedure and equipment are described. Massive MIMO (MaMi) channel characteristics and key parameters are extracted and used in an extended COST 2100 channel model for MaMi.

Two possible mitigation approaches are introduced, which may both be adequate depending on the system set-up. - D2.5 - Description of MaMi digital modulation and architectures for efficient MaMi transmission
This deliverable describes the digital modulator architectures. It also presents the motivation behind time based signal processing in tandem with digital modulators and a digital modulator implementation, that is based on the needs of a transmitter for MaMi (power efficient and low-cost). - D3.2 - Distributed and centralized baseband processing algorithms, architectures, and platforms
Baseband processing and the corresponding processing distribution for Massive MIMO systems are discussed. Digital signal processing algorithms are discussed in the context of practical deployment scenarios and in conjunction with hardware architecture, implementation cost, and power consumption. - D5.5 - Updated plan and initial report on dissemination, standardization and exploitation

Over the course of the Mammoet project, different aspects of the MaMi technology have been investigated, including theoretical studies, simulations, hardware design and testbed-based experi- ments. This deliverable validates aspects connecting the work of multiple workpackages and project components.
