CALL FOR PAPERS EURASIP JOURNAL ON APPLIED SIGNAL PROCESSING Special Issue on: Space-Time Coding and Its Applications Space-time coding for multiple transmit and multiple receive antenna systems has recently attracted considerable attention in the wireless communication area. It has been shown theoretically that for certain channels the capacity of a multiple antenna system increases linearly with the number of antennas, which implies that multiple antenna systems have huge potential applications in broadband wireless communications. In a multiple antenna system, a key step is multiple antenna coding and modulation, called space-time coding. In single antenna systems, the coding and modulation only deals with one by one complex symbols or symbol sequences. However, in multiple antenna systems, the space-time coding deals with M by L complex symbol matrices or matrix sequences. In space-time coding, space-time code design is one of the most important topics. Unlike the conventional single antenna AWGN channel, the multiple antenna channel is a matrix instead of a scalar even in the simplest case. So, the space-time code design is more challenging than in single antenna systems. Concerning a multiple antenna channel, i.e., a multi-input and multi-output (MIMO) system, there are two cases: the MIMO channel is known or unknown at the receiver. Since the channel is a complex matrix, signal processing may play an even more important role than it does in a single antenna system. When we deal with space-time matrices, the code size may be huge and therefore fast decoding algorithms are critically important. Although a significant amount of work on space-time coding exists already, there are many more challenging problems remaining to improve multiple antenna systems and make them work in practice. The aim of this special issue is to bring researchers in space-time code design and signal processing together to present innovative results for potentially achieving improved practical multiple antenna systems. Prospective papers should be unpublished and present solid research work offering innovative contributions either from a methodological or application point of view. Topics of interest include (but are not limited to): General and orthogonal space-time code designs Differential space-time modulation Turbo space-time coding Fast space-time code decoding algorithms MIMO channel estimation Space-time code design for MIMO channels with memory Space-time coded MIMO channel equalization System analysis of a space-time coded system combined with other techniques Capacity analysis Applications of space-time coding in wireless image/video communication systems Authors should follow the EURASIP JASP manuscript format described at the Journal site http://asp.hindawi.com/.
