Universal space-time coding
A universal framework is developed for constructing full-rate and full-diversity coherent space–time codes for systems with arbitrary numbers of transmit and receive antennas. The proposed framework combines space–time layering concepts with algebraic component codes optimized for single-input–single-output (SISO) channels. Each component code is assigned to a “thread” in the space–time matrix,...
متن کاملConcatenated space-time coding
The serial concatenation of standard convolutional codes with differential spacetime modulation is considered for fast flat fading multiple antenna channels. Decoding is performed iteratively by passing symbol-wise a-posteriori probability information between the decoders of the inner space-time code and the outer convolutional code. An input-output extrinsic information transfer analysis is us...
متن کاملDifferential Turbo Space-Time Coding
Serial concatenation of standard convolutional or block codes with differential spacetime modulation is considered for flat fading multiple antenna channels. Extrinsic information transfer is used to predict thresholds for various outer codes. Using the differential structure of the inner code near coherent performance is obtained without the use of training symbols.
متن کاملLayered Space-Time Index Coding
Multicasting K independent messages via multiple-input multiple-output (MIMO) channels to multiple users where each user already has a subset of messages as side information is studied. A general framework of constructing layered space-time index coding (LSTIC) from a large class of space-time block codes (STBC), including perfect STBC, is proposed. We analyze the proposed LSTIC and show that i...
متن کاملReal Time Object Based Coding
This paper describes the design of a real-time MP4 Structured Audio codec for monophonic signals. The coding of the live input consists of a pitch detection system which returns the MIDI-like data, and an additive synthesis scheme which creates and modifies the current instrument. Both parts are designed to be fast and scalable. The analysis parameters let the user choose the computational cost...
