A new multiple-input multiple-output (MIMO) transmission scheme named\textit{ trellis coded space-shift keying} (TC-SSK) is proposed in this paper. This scheme is obtained by the combination of trellis coding and SSK for a given spectral efficiency, number of transmit antennas and trellis states. A soft decision Viterbi decoder is employed at the receiver to decode the transmitted SSK symbols. Using...
In this paper we analyze generalized type-II hybrid ARQ procedure using rate-punctured convolutional (RCPC) codes for balanced, unbalanced, and correlated MIMO orthogonal STBC systems with Rayleigh propagation. Parameters of the corresponding finite state Markov chain (FSMC) model are derived using an SNR partition method based on equal-state duration. Analytical results for throughput and packet...
When channel state information is not available, combined unitary space-time modulation and parallel concatenated convolutional code can greatly improve the system performance, however it also meet with the error floor phenomenon. We propose a scheme of utilizing unitary space-time symbol based serial concatenated convolutional code for multiple-antenna wireless communication systems over rapid fading...
Hybrid Automatic Repeat reQuest (HARQ) schemes are becoming common in wireless systems. In addition to the channel characteristics, several system design considerations need to be taken into account when choosing the particular HARQ scheme to be used. For SISO systems, it has been shown that the coding gain of Incremental Redundancy (IR-) HARQ over Chase Combining (CC-) HARQ may be offset by adverse...
Li and Xia have recently investigated the design of space-time codes that achieve full spatial diversity for asynchronous cooperative communications. They show that certain of the binary space-time trellis codes derived from the Hammons-El Gamal stacking construction are delay tolerant and can be used in the multilevel code constructions by Lu and Kumar to produce delay tolerant space-time codes for...
Orthogonal frequency division multiplexing (OFDM) is the modulation scheme of choice for digital video broadcasting-handheld (DVB-H), which is required to operate under high mobility conditions resulting in significant Inter-carrier Interference (ICI). To mitigate ICI, several cancellation schemes have been proposed but they require reliable channel information at the receiver which is quite challenging...
