چکیده
| In this paper, a novel noncoherent linear equalization scheme is introduced and analyzed. The proposed scheme is not only applicable for M{ ary di erential phase{shift keying (MDPSK) but also for M{ary di erential amplitude/phase{shift keying (MDAPSK) and minimizes the variance of intersymbol interference (ISI) in the equalizer output signal. The optimum equalizer coeÆcients may be calculated directly from an eigenvalue problem. For an eÆcient recursive adaptation of the equalizer coeÆcients, a modi ed least{mean{square (LMS) algorithm is proposed. Simulations con rm the good performance of the considered noncoherent equalization scheme and its robustness against frequency o set.

Adaptive noncoherent linear minimum ISI equalization for MDPSK and MDAPSK signals
In this paper, a novel noncoherent linear equalization scheme is introduced and analyzed. In contrast to previously proposed noncoherent equalization schemes, the proposed scheme is not only applicable for M{ary di erential phase{shift keying (MDPSK) but also for M{ ary di erential amplitude/phase{shift keying (MDAPSK).

متن کاملAdaptive linear equalization combined with noncoherent detection for MDPSK signals
A novel noncoherent receiver for M{ary di erential phase shift{keying (MDPSK) signals transmitted over intersymbol interference (ISI) channels is presented. The noncoherent receiver consists of a linear equalizer and a decision{feedback di erential detector. A signi cant performance gain over a previously proposed noncoherent receiver can be observed. For an in nite number of feedback symbols, ...
متن کاملAdaptive noncoherent DFE for MDPSK signals transmitted over ISI channels
In this paper, a novel noncoherent decision{feedback equalization (NDFE) scheme for M{ary di erential phase shift{keying (MDPSK) signals transmitted over intersymbol interference (ISI) channels is presented. A suboptimum version with lower computational complexity and a noncoherent linear equalizer (NLE) are derived from the original NDFE scheme. Furthermore, the relation of the novel NLE to a ...
متن کاملTrellis-coded CPFSK and soft-decision feedback equalization for micro-cellular wireless applications
In this paper, trellis-coded M-ary CPFSK with noncoherent envelope detection and adaptive channel equalization are investigated to improve the bit error rate (BER) performance of microcellular digital wireless communications systems. For the same spectral efficiency, the trellis-coded modulation (TCM) schemes studied outperform minimum shift keying (MSK) with noncoherent or differentially coher...
متن کاملTurbo Equalization of Gmsk Signals Using Limiter-discriminator
Sequence estimation (SE) of narrow-band digital FM signals, such as GMSK or CPFSK, with noncoherent limiter/ discriminator (L/D) and post-lowpass filter detection, was investigated in [1]-[3]. This paper proposes a novel Turbo equalization scheme of GMSK signals, where the iterative decoding between the inner ISI decoder and the outer Recursive Systematic Convolutional (RSC) decoder has been do...
