We characterize the capacity of broadcast channel in MU-MIMO system with fixed relays. By analyzing the similarities between the model of MU-MIMO with relays and the circuit with multiple capacitors, we give a method to estimate the end to multi-end broadcast capacity. In our method, we first partition the relay system into simple point to point components and calculate the capacity of each point...
Multiple input multiple output (MIMO) is the key techniques to achieve high throughput for 3GPP long term evaluation (LTE). In the downlink, the number of the receive antennas is limited by the weight, size and battery consumption requirements of the mobile terminal. Using multiple receive antennas will obviously be a limiting factor in the development of small terminals. In this paper, we propose...
