About the Author
Luigi MORENO is a Radio Communications Consultant with more than 25 years' experience. A graduate of the "Politecnico di Torino" (Italy), he was at CSELT (Telecom Italia Research Labs) (1973-82), then at GTE Telecomunicazioni (1982-85). He has been a delegate at many ITU-R meetings and a teacher at SSGRR (Telecom Italia Training School). His activity as a consultant includes many assignments with manufacturing and operating companies (software developments for radio system simulation, analysis, and testing; design of radio links and networks; training courses). He is an IEEE Senior Member and serves as an IEEE Transactions Technical Reviewer. He is the author of some 30 journal and conference papers and of two patents for mobile radio receivers.
