Frequency Space Lattice Encoding for Noncoherent Detection with Correlated Signals
نویسندگان
چکیده
| It is shown that a high density lattice sphere packing is a good mean to improve the performance of a frequency shift-keying modulation with correlated signals and noncoherent detection. It is proved that the pairwise error probability of the mul-tidimensional FSK alphabet is related to the lattice fundamental gain. A soft output noncoherent detector is described and used to estimate the performance on a Gaussian channel.

Noncoherent Detection of FSK Signals Transmitted over Linearly Time-Selective Rayleigh Fading Channels
Linearly time-varying fading models are used to investigate noncoherent detection of frequency-shift keying (FSK) signals transmitted over frequency-flat fading channels. The structure of the optimal noncoherent FSK detector is derived and a novel analytical technique is proposed to compute the error performance of noncoherent FSK detectors in fast fading. Error performance results obtained by ...
متن کاملNoncoherent decorrelative detection for nonorthogonal multipulse modulation over the multiuser Gaussian channel
This paper introduces the problem of noncoherent detection for nonorthogonal multipulse modulation in the context of the synchronous multiuser Gaussian channel. Each user sends an M -ary information symbol by transmitting one ofM possibly nonorthogonal waveforms. Furthermore, the M signals of one user are allowed to be correlated with the signals of all other users. A key idea proposed here is ...
متن کاملForward Error Correction of FSK Alphabetsfor Wireless Noncoherent
|In this paper, we show that several coding schemes, and in particular turbo encoding , dramatically improve the performance of a noncoherently detected frequency shift-keying modulation with correlated signals. The APP decoding scheme based on bit-by-bit decisions proves to be better than a classical block decisions decoding scheme when the bit mapping is not optimized. Moreover, the choice of...
متن کاملNoncoherent Communication in Space and Time
This paper considers noncoherent communication over a frequency nonselective channel in which the time-varying channel gain is unknown a priori, but is approximately constant over a coherence interval. Unless the coherence interval is large, coherent communication, which requires explicit channel estimation and tracking prior to detection, incurs training overhead which may be excessive, especi...
متن کاملAdaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
