Transmitter Comparison and Unequal Bit Error Probabilities in Coherent QPSK Systems

Not Accessible

Your library or personal account may give you access

Abstract

We compare different QPSK transmitters and find that some simple configurations can give rise to a significant difference in BER between the two transmitted bits. The optimum receiver filter bandwidth is affected by this phenomenon.
