Frequency-hopping Trellis-coded 8-dpsk for Indoor Communications
نویسنده
چکیده
In this paper we propose a TDMA Slow Frequency Hopping-Trellis Coded 8DPSK scheme for indoor mobile radio communications. In order to assess the performance of this scheme a GWSSUS (Gaussian Wide Sense Stationary Uncorrelated Scattering) continuous channel model with an exponentiol Power Delay Profire has been adopted. This channel model allows us to analize transmission rates much lower than the inverse of the r.m.s. delay spread. Bit error rate (BER) is obtained, through Monte Carlo computer simulation, as a function of signal to noise ratio (SNR) and with normalized frequency-hopping separation and number of hopping-frequency channels as parameters.

Trellis-coded pulse-position modulation for indoor wireless infrared communications
We analyze the performance of trellis-coded pulseposition modulation (PPM) on indoor, wireless infrared channels. We show that maximum-likelihood sequence detection (MLSD) of trellis-coded PPM is very effective in mitigating the multipath dispersion on such channels. We present code search results for high constraint-length, rate-2/3, 8-PPM and rate-3/4, 16PPM codes. We provide bit-error rate c...
متن کاملOptical Multilevel Dpsk Systems with Coded Modulation
We propose and theoretically demonstrate the application of a specific coded modulation technique called as the Trellis Coded Modulation (TCM) to optical multilevel Differential Phase Shift Keying (DPSK) systems. In the process of identifying receiver structures for optical DPSK systems with coded modulation, it was discovered that though the parallel outputs from delay interferometer based opt...

متن کاملBit Error Probability of Trellis-Coded Quadrature Amplitude Modulation Over Cross-Coupled Multidimensional Channels
Convolutionally encoded M-ary quadrature amplitude modulation (M-QAM) systems operated over multidimensional channels, for example dual-polarized radio systems, are considered in this paper. We have derived upper bounds on the average bit-error probability for 4QAM (QPSK) with conventional convolutional coding by means of a truncated union bound technique and averaging over the cross-polarizati...
متن کاملOn coding for block fading channels
This work considers the achievable performance for coded systems adapted to a multipath block–fading channel model. This is a particularly useful model for analysing mobile–radio systems which employ techniques such as slow frequency–hopping under stringent time–delay or bandwidth constraints for slowly time–varying channels. In such systems, coded information is transmitted over a small number...
