In this paper, we proposed a symbol-based multiple phase shift keying (MPSK) soft-informationforwarding (SIF) scheme for a two-hop parallel relay wireless network in Rayleigh fading channel. First the binary information streams at the source are mapped into MPSK symbols, and the relays construct the relay processing function by passing the intermediate soft decisions. Then the relays broadcast ...

-The first part of this paper presents a simple and systematic technique for constructing multidimensional M-ary phase shift keying (MPSK) trellis coded modulation (TCM) codes. The construction is based on a multilevel concatenation approach, in which binary convohitionai codes with good free branch distances are used as the outer codes and block MPSK modulation codes are used as the inner code...

© 2009 Jung-Su Kim et al. 345 ABSTRACT⎯This letter presents an alternative analytical expression for computing the probability of an M-ary phase shift keying (MPSK) wedge-shaped region in an additive white Gaussian noise channel. The expression is represented by the cumulative distribution function of known noncentral Fdistribution. Computer simulation results demonstrate the validity of our an...

The traditional technique of generating MPSK signals is basically to use IQ modulator that involves analog processing like multiplication and addition where inaccuracies may exist and would lead to imbalance problems that affects the output modulated signal and hence the overall performance of the system. In this paper, a simple method is presented for generating the MPSK using logic circuits t...

This paper focuses on the combined radar and communications problem conducts a thorough analytical investigation effect of phase frequency change communication sensing functionality. First, we consider classical stepped waveform modulate data using M-ary shift keying (MPSK). Two important tools in design, namely ambiguity function (AF) Fisher information matrix (FIM) are derived, based which, m...

One method to enable fast acquisition of a phase-locked loop (PLL) in spite of large frequency offsets and small PLL bandwidths is to use an additional AFC loop. A suitable frequency error detector (FED) for large frequency offsets is the well-known balanced quadricorrelator. This FED is shown to produce great pattern jitter if it is to work with digital modulated MQAM and MPSK signals (M > 2) ...

Under communication environments, such as wireless sensor networks, the noise observed usually exhibits impulsive as well as Gaussian characteristics. In the initialization of channel iterative decoder, such as low density parity check codes, it is required in advance to estimate the channel parameters to obtain the prior information from the received signals. In this paper, a blind channel par...

Conclusion: We have derived new expressions for the symbol error rate performance of coherent M-ary phase shift keyed signals in slow nonselective Nakagami fading and additive white Gaussian noise channel. For integer values of the Nakagami fading parameter m, a closed-form expression is derived for the symbol error rate. However, for real values of nz, a simple formula which can be easily comp...

A phase sensitive amplification (PSA) regeneration model for M-ary shift keying (MPSK) signals with amplified spontaneous emission (ASE) noise based on the interference between signal and its (M+1)th harmonic is proposed. Compared existing models different combinations of harmonics, new optimal in theory to deal MPSK degraded by ASE noise. The QPSK format taken as an example simulation verifica...
