【简　介】:Abstract—In this paper, we present several properties on
minimum distance(dumin) and girth(Gumin) in Tanner graphs for
low-density parity-check (LDPC) codes with small left degrees.
We show that the distance growth of (2, 4) LDPC codes is too slow
to achieve the desired performance. We further give a tight upper
bound on the maximum possible girth. The numerical results
show that codes with large Gumin could outperform the average
performance of regular ensembles of the LDPC codes over binary
symmetric channels. The same codes perform about 1.5 dB away
from the sphere-packing bound on additive white Gaussian noise
channels.
Index Terms—Concatenated systems, final length analysis, iterative decoding, short low-density parity-check (LDPC) codes, turbo decoding.

【格　式】:rar
【大　小】:96K
【简　介】:Abstract—An adaptive serial search pseudonoise (PN) code
acquisition scheme is proposed, in which the detection threshold
is scaled by the instantaneous received power measured prior
to PN code correlation. We observe that the proposed scheme
achieves significantly improved mean acquisition times compared
to the conventional nonadaptive schemes under Rayleigh fading
and pulsed Gaussian noise jamming. Furthermore, the proposed
scheme is shown to be optimum under pulsed Gaussian noise
jamming in the sense that it forces the worst case jamming fraction
to unity.
Index Terms—Adaptive system, fading channels, jamming,
pseudonoise coded communication, synchronization.
