چکیده
Pilot power allocation for Internet of Things (IoT) devices in massive multi-input multioutput heterogeneous wireless sensor networks (MIMO-HWSN) is studied this paper. The interference caused by fractional pilot reusing adjacent cells had a negative effect on the MIMO-HWSN system performance. Reasonable users can effectively weaken interference. Motivated water-filling algorithm, we proposed suboptimal transmission method to improve capacity. Simulation results show that significantly uplink capacity and explain influence different performance system, but complexity almost does not increase.

متن کاملChannel Capacity Estimation in MIMO Systems Based on Water-Filling Algorithm
In radio, multiple-input and multipleoutput (MIMO), is the use of multiple antennas at both the transmitter and receiver to improve communication performance. Multiple antennas may be used to perform smart antenna functions such as spreading the total transmit power over the antennas to achieve an array gain that incrementally improves the spectral efficiency. In this paper the water filling al...

In this paper we consider MIMO system with Mt transmitting and Mr receiving antennas, when channel state information (CSI) is known on the transmitter side. The Reyleigh fading channel propagation condition is assumed. In this case, the optimum transmission consists of allocating the transmitted power for each virtual sub-channel related to the corresponding eigenvalue of the channel matrix. Th...
