Tight bounds and accurate approximations for DQPSK transmission bit error rate - Electronics Letters

چکیده
Recently proposed bounds for the Marcum Q-function are applied to derive novel tight bounds for the bit error rate for differential quaternary phase shift keying transmission with Gray coding over an additive white Gaussian noise channel. Simple and accurate approximations are then proposed for the BER. The computational complexity of the final approximate expression is significantly lower than that of the exact expression.

Decision Directed Coherent Detection in Multicarrier Systems on Rayleigh Fading Channels
Novel coherent detectors for DQPSK and-DQPSK on Rayleigh fading channels are presented. The detectors are based on decision feedback and minimum mean square error (MMSE) channel estimation. The proposed detectors may be used in both single carrier and multicarrier systems. Analytical results in form of expressions for channel estimation error variance and bit error probability, both with and wi...
متن کاملApproximate Equation of Bit Error Rate in DQPSK/OFDM Systems over Fading Channels
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 DQPSK/OFDM systems over frequency nonse...
متن کاملTight bounds for the first order Marcum Q-function
In this paper, we develop new bounds for the first order Marcum Q-function, which are extremely tight and tighter than any of the existing bounds to the best of our knowledge. The key idea of our approach is to derive refined approximations for the 0 order modified Bessel function in the integration region of the Marcum Q-function. The new bounds are very tight and can serve as an effective mea...

Mday, M arch 24 transmission system was 20 Gb/s, while the symbol rate was 10 Gbaud (=10 GS/s). The second MZ modulator was used as a pulse carver to generate RZ-DQPSK signals. For the 20-Gb/s DQPSK receivers, two 100-ps DIs with two separate balanced receivers are generally required to simultaneously demodulate the two 10-Gb/s data streams contained in the 10-Gbaud DQPSK signal [4]. However, w...
متن کاملSIMULATION OF BIT ERROR PERFORMANCE AND OUTAGE PROBABILITY OF rt/4 DQPSK IN FREQUENCY-SELECTIVE INDOOR RADIO CHANNELS USING A MEASUREMENT-BASED CHANNEL MODEL
A real-time simulation tool called BERSIM is developed and used to study bit-by-bit errors, average bit error rate and block outage probabilities for Tt/4 DQPSK at megabit rates with raised-cosine pulse shaping. Simulation results show that when the ratio of nns delay spread to bit duration is greater than about 0.02, the irreducible average BER is not only a function of rms delay spread, but i...
