Approximate Equation of Bit Error Rate in DQPSK/OFDM Systems over Fading Channels

Abstract

With OFDM, which is a kind of multi-carrier systems, it is possible to use a diãerential coding/diãerential detection either in the time or frequency domain depending on the condition of transmission channels with the adoption of DQPSK as a method of subcarrier modulation. This paper proposes an approximate derivation method of the bit error rate (BER) in… (More)
