| Summary |
Stochastic Resonance (SR), known as a noise-enhanced phenomenon, can improve the performance of commutation systems. In this paper, we present a preliminary study on SR and its application to BPSK receiver. We discuss a basic question
arises from a receiver using SR that shall we perform SR process in a radio-frequency (RF) band or in a baseband (BB)?
As results, we found that SR process in RF band shows better Bit Error Rate (BER) performance. This comes from the fact that a down conversion process that reduces the signal amplitude causes weak noise suppression by SR. While a double
frequency term obtained also by the down conversion process do not affect much to the noise reduction performance. |
