Further Results on a Reduced-Complexity, Highly Power-/Bandwidth-Efficient Coded Feher-Patented Quadrature-Phase-Shift-Keying System with Iterative Decoding
Based on a representation of Feher-patented quadrature-phase-shift keying (FQPSK) as a trellis-coded modulation, this article continues the investigation of the potential improvement in power efficiency obtained from the application of simple (small number of states) outer codes to form a concatenated coding arrangement with iterative decoding. For the additional two of the three concatenation ...

Based on a representation of Feher-patented quadrature-phase-shift keying (FQPSK) as a trellis-coded modulation, this article investigates the potential improvement in power efficiency obtained from the application of simple (a small number of states) outer codes to form a concatenated coding arrangement with iterative decoding. Several possible configurations for the concatenation are suggeste...
متن کاملEXIT Chart-based Design of LDPC Codes for Inter-Symbol Interference Channels
The subject of this paper is the design of lowdensity parity-check (LDPC) codes concatenated with a Gray mapped quaternary phase shift keying (QPSK) modulator for transmission over inter-symbol (ISI) channels. In particular, we will present several results considering important partial response channels (PRCs). Using an extrinsic information transfer (EXIT) chart-based analysis, we give insight...
متن کاملConcatenated space-time codes for quasi-static fading channels: constrained capacity and code design
Abstract— The problem of designing codes with close-tocapacity performance on the multiple-input multiple-output (MIMO) quasi-static fading channel (QSFC) is addressed. We consider three different coding schemes – namely, direct transmission of random-like codes, concatenation with linear processing orthogonal space-time block codes (o-STBC) and concatenation with space-time trellis codes (STTC...
متن کاملPerformance Analysis of a Concatenated Ldpc Coded Alamouti-based Stbc-ofdm System on Text Message Transmission
This paper investigates the impact of concatenation of an interleaved low density parity check (LDPC) code with convolutional channel coding on the performance of the space time block coded (STBC) orthogonal frequency-division multiplexing (OFDM) wireless communication system on text message transmission. The concatenated channel encoded OFDM system deploys various digital modulations (BPSK, QP...
