It is necessary to calculate and evaluate the effects on communication efficiency of antenna caused by the irregular terrain, so as to avoid the adverse effects on communication caused by terrain reasonably and make full use of all communication resources of shortwave stations. The remote communication performance of HF antenna is analyzed quantitatively, using the antenna radiation simulation results...
A novel 2.4 GHz metal-mount tag antenna has been designed and tested successfully. Low profile of 3mm is achieved. It can work reliably mounting on different metallic surfaces with a high antenna gain of 5 dBi and impedance stability (VSWR < 2) within the bandwidth required.
An a posteriori probability (APP) detector for multiple antenna channels has presented in . It has the high advantage of providing good performance but has an NP complexity, we studied near capacity and near outage performance over multiple antenna channels thanks to optimized bit interleaved coded modulations (BICM) . We will now present a sub-optimal soft-input soft-ouput (SISO) detector based on...
