Receiver selectivity

WebbWLAN RF receivers can be designed with effective ACR for narrow band signals which are approximately 0.10 the bandwidth of 802.11 signals. These narrow band signals include cordless phones and Bluetooth signals. However, wide band ACI generates significant side band energy which falls into the pass band of an 802.11 receiver. WebbR (f) is the receiver selectivity with the receiver tuned to the transmitter frequency. OFR ( f) = 10 log10 (2.3) OTR = 10 log10 (2.4) Once the FDR value has been determined for a transmitter-receiver pair, a frequency-distance separation relationship can be calculated from the following formula: LP ( f) = LR – FDR ( f) (2.5) where,

Webb10 apr. 2024 · Selective LIS corresponds to using a subset of the total number of antennas. The algorithm employed in the selective LIS corresponds to those antennas that are placed at shorter distance from the mobile terminal. As expected, the use of selective LIS results in a performance degradation relating to the system without selective LIS. WebbReceiver selectivity is determined by various parameters in the receive chain, namely filtering, linearity, and noise. The appropriate level of selectivity needed can be quantified in terms of co-channel rejection for example. Co-channel rejection is the ratio between the desired signal to the unwanted interferer or blocker.
