Multiple Symbol Differential Detection of MPSK which is Invariant to Frequency Offset using Maximum-likelihood detection
It is well known that classical differential detection of MPSK signals, wherein the information is encoded as the first order phase difference, is a simple and robust form of communication in environments not subject to frequency variation. For channels that introduce into the carrier a random frequency shift, eg., those associated with moving vehicles, classical differential detection as above...
متن کاملA non-data-aided and non-phase-based AFC method for MPSK DS/CDMA transceivers used in digital broadcasting
Due to its high-performance broadcast capability, -ary phase-shift-keying (MPSK) direct sequence code division multiple access (DS/CDMA) technique is widely used in terrestrial and satellite communications to provide wired/wireless services such as audio broadcasting, video broadcasting and high-speed data transmission. However, both coherent and noncoherent MPSK modulation schemes are sensitiv...
متن کاملEquivalent channel for capacity analysis of differential detection over time-varying communication channels
This paper introduces the concept of equivalent channel for mutual information performance analysis of multiplesymbol differential MPSK (M -phase shift keying) over timecorrelated, time-varying flat-fading communication channels. It is proven that differential detection scheme theoretically preserves the channel information capacity when the observation interval approaches infinity. A state spa...
متن کاملComparative Performance Analysis of MPSK and MQAM-Modulation Parameters on Orthogonal Frequency Division Multiplexing (OFDM) System over Flat and Frequency Selective Rayleigh Fading Channels with Doppler Frequency
OFDM is a multicarrier modulation technology which has efficient spectrum utilization to support the transmission of high data rates. The typical subcarrier modulation schemes used in orthogonal frequency division multiplexing (OFDM) system includes: b inary phase shift keying (BPSK), phase shift keying (PSK) and quadrature amplitude modulation (QAM). This paper analyses the comparative perform...
متن کاملI-49: Doppler Study in Female Pelvic Tumoral Mass
Background Ultrasound is the first line modality in evaluation of pelvic masses in female patients. It is helpful in detection of masses and also in determining origin of them. Tissue characterization is possible with gray scale but Doppler study is quite necessary and considers as complimentary method. Most of the time, it should be performed in vaginal US exam. Existence of vascularity and al...
