Relative Performance of BPSK and BFSK in Underground Mine Communication Considering Multipath and Bending Losses
Abstract: AbstractWireless/Mobile signals get strongly attenuated deep inside a building/tunnel/mine. In order to study the performance parameters, underground communication channel needs to be modeled. As a first step here we have practically tried two digital modulation methods BPSK and BFSK for underground communication. Wireless link was able to support data signals. Various measurements were made up to a depth of 30 m inside the mine. Beyond 30 m as more than …
