这里有一篇文章值得看一看:无线通信中的SNR、SINAD和SINR 自干扰 无线信号不是按照一个确定的直线方向进行传播的,就像上面所给出的自由空间损耗模型;信号在传播时会接触到不同的表面而产生反射,这些反射会导致信号传播的时差,从而到达目的地时会产生叠加,形成自干扰。如下图: 其它发射源干扰 如果在同一时间有其他设备...
node densification and dynamic RAN (cf. RAN 2.0 described previously) can allow confining interference to very specific areas of use while reducing the signal attenuation. Both effects shall boost the signal to interference plus noise ratio (SINR) thus increasing the user data rate by a logarithmic...
If a mobile station 14, 16, 18 fails decode a page on PCH, due to low signal to noise and interference ratio (SINR), the network 10 can optionally repeat the broadcast until the mobile station 14, 16, 18 replies. [0027] According to one embodiment of the present invention, paging ...
The hit probability, the coverage probability, throughput, and energy efficiency are derived as closed- form expressions or the functions of the SINR ratio threshold, path loss exponent, transmission power and density of macro and small cells, cache ability, content popularity, and backhaul capacity...
partitioning mechanism. The radio resource partitioning enables radio resource allocation among different devices in a coordinated way. The restrictions can be either on the basis of available PRBs or transmit power. As a result, such restrictions provide the possibility for improving the SINR ratio. ...
SINRInternet of ThingsThroughputNetwork lifetimeWireless sensor networks are network of the large number of sensors having lesser batteries. Such networks and clustering of the nodes for energy efficiency go hand in hand. Clustering protocols like low energy adaptive clustering hierarchy, stable election...

When a mobile station transmits in the non-orthogonal mode, this situation may apply to either pilot (used for demodulation or for SINR estimation) or for bearer/traffic channels or to both channels. However, if the transmissions from a subset of mobile stations on the reverse link are ...
In performing a one-shot assignment for a small number of caller pairs, the FEMs may be arranged in order of decreasing common SINR they provide to the caller pair under consideration, and the top two FEMs may be considered for allocation. Additionally, when a plurality of FEMs are located ...
This results in a stronger received signal strength (e.g., reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR), etc.) of the RF signals received from that direction. Receive beams may be spatially related. A spatial...
