Nonlinear Turbo Codes for Higher-Order Modulations
— In 1982 Ungerboeck presented a set-partitioning design technique for trellis coded modulation (TCM). Although this technique directly assigns constellation points to the branch...

Think globally, search locally
A key step in program optimization is the determination of optimal values for code optimization parameters such as cache tile sizes and loop unrolling factors. One approach, which...

Hybrid-ARQ Code Combining for MIMO Using Multidimensional Space-Time Trellis Codes
— A hybrid automatic repeat-request (ARQ) code combining scheme employing different multidimensional spacetime trellis codes (MSTTCs) over a multiple-input, multipleoutput (MIMO)...

Joint Source Channel Coding with Side Information Using Hybrid Digital Analog Codes
We study the joint source channel coding problem of transmitting an analog source over a Gaussian channel in two cases - (i) the presence of interference known only to the transmit...

DMT optimality of LR-aided linear decoders for a general class of channels, lattice designs, and system models
The work identifies the first general, explicit, and non-random MIMO encoder-decoder structures that guarantee optimality with respect to the diversity-multiplexing tradeoff (DMT),...
