This book presents the design and bit error rate (BER) performance of a Differentially Quadrature phase shift keying (DQPSK) signals over additive white Gaussian channel (AWGN) with L number of diversity branches. The performance of a DQPSK signals is also studied with post detection equal Gain combining in additive white Gaussian noise and slow frequency- non selective identical and non identical weibull fading channels, in which diversity branch can have unequal signal-to-noise ratios (SNRs) as well as different severity parameter. The mention system above is applied on the ad hoc wireless n...
This book presents the design and bit error rate (BER) performance of a Differentially Quadrature phase shift keying (DQPSK) signals over additive white Gaussian channel (AWGN) with L number of diversity branches. The performance of a DQPSK signals is also studied with post detection equal Gain combining in additive white Gaussian noise and slow frequency- non selective identical and non identical weibull fading channels, in which diversity branch can have unequal signal-to-noise ratios (SNRs) as well as different severity parameter. The mention system above is applied on the ad hoc wireless network,Then studies the impact of the DQPSK modulation on the BER and effective transport capacity when transmitting over weibull fading channels when the node are distributed randomly, since it seems to be more practical than the uniform distribution. The results are compared to those node are distributed uniformly (Hexagonal and Square grid topology).
