چکیده
The channel correlation happens in a MIMO-femtocell (multiple-input multiple-� output) system with beam-subset beamforming technique is investigated in this paper.� MIMO-femtocell system constructed with MIMO signaling that is adapted to a tiered� femtocellular network. The MIMO-femtocell system deployed with home base station� (BS) in a single floor indoor environment is proposed. According to the analyses of both� theoretical and simulation results, channel correlation definitely degrades the overall� system performance of a MIMO-femtocell system with beam-subset, especially in indoor� channels. Moreover, the coverage area of a MIMO-femtocell deployment is reduced� because of channel correlation occurring in the propagation channel. Some analyzed of� closed forms are utilized to discuss the phenomenon of channel correlation that exists in� MIMO-femtocell systems. Specifically, many numerical results, which are applied to� validate the performance of being derived throughput, and the curves match well with the� simulation results obtained from the software package. It is noteworthy to remember that if� the channel correlation phenomenon is neglected in the performance evaluation of a� MIMO-femtocell system over the Rayleigh statistical model, there will be one to about� four folds degradation existing in the BS coverage area. Moreover, the number of beamsubset� is the other parameter dominates the system performance of a MIMO-femtocell� system when the beamforming signaling is applied in the operation.

متن کاملCapacity of Different MIMO Systems Based on Indoor Measurements at 5.2GHz
We compared the average capacities of measured 8 8, 4 4 and 2 2 systems with fixed array size in an indoor office scenario at different receive positions. As expected, correlation either at the transmit or receive side is limiting the MIMO capacity. While the 2 2 system reaches mostly the capacity of an i.i.d. Rayleigh fading channel, the 4 4 and particularly the 8 8 system does not. When we tr...
متن کاملOn the capacity of spatially correlated MIMO Rayleigh-fading channels
In this paper, we investigate the capacity distribution of spatially correlated, multiple-input–multiple-output (MIMO) channels. In particular, we derive a concise closed-form expression for the characteristic function (c.f.) of MIMO system capacity with arbitrary correlation among the transmitting antennas or among the receiving antennas in frequency-flat Rayleigh-fading environments. Using th...

In this paper, we present a hybrid indoor MIMO channel model for predicting the performance of multiple-element antenna system. The model incorporates the wave clustering phenomena and combines the statistical characteristics of clusters with deterministic ray tracing method. The capacity of the MIMO channel is expressed as a function of spatial correlation at both the transmitter and the recei...
