On Some Design Issues of Space-Time Coded Multi-Antenna Systems
This paper concerns some design issues and tradeoffs of communication systems equipped with multiple transmit and receive antennas. The general space-time coding/modulation structure by Tarokh et al. (1999) is considered. Several design issues are investigated for this structure. The layered space-time architecture by Foschini (1996) is revisited as a special case of the general structure. It i...
متن کاملSpace-Time Coded CDMA Systems
Absfrmf-' I n this paper, we present a comparative performance evaluation of adaptive multiuser detectors, including stochastic gradient (SG) and recursive least squares (RLS) algorithms (which require training data), and minimum output energy (MOE) and subspace-based MMSE (S-MMSE) algorithms (which do not require training data), under near-far conditions in a space-time coded CDMA system. We s...
متن کاملDesign of Space-Time Coded Single-Carrier and Multi-Carrier MIMO-CDMA systems
CDMA is one of the channelization protocols that support more number of users simultaneously and asynchronously. Uses spreading technique that spreads information bearing signals, so that only intended receiver can able to receive it thus provides security. MIMO technology has been widely used in wireless communications provides higher data rate and reliability. In this paper single and multi c...
متن کاملReduced dimension space-time processing for multi-antenna wireless systems
The need for wireless communication systems has grown rapidly during the last few years. Moreover, there is a steady growth in the required data rates due to the fact that more and more users request high-bit-rate services. To meet those requirements, current and next-generation wireless systems and networks such as wireless LANs (e.g., IEEE 802.11a) will support much higher data rates compared...
متن کاملSpace-time overlays for convolutionally coded systems
In this paper, we consider the design of space–time overlays to upgrade single-antenna wireless communication systems to efficiently accommodate multiple transmit antennas. We define the overlay constraint such that the signal transmitted from the first antenna in the upgraded system is the same as that in the single-antenna system. The signals transmitted from the remaining antennas are design...
