Adaptation of Algebraic Space Time Codes to Frequency Selective Channel
نویسندگان
چکیده
The Algebraic Space Time Codes (ASTC) are constructed based on cyclic algebras; they showed a good spectral efficiency, a full diversity, and a full rate under non selective channel condition. However, the radio mobile channel is a selective channel whose features vary during the time. This selectivity is owed to the multi-path phenomenon and generates interferences between symbols (IES). The overall objective of this chapter is to proof that ASTC is adapted to channel selectivity, in order to analyze and improve its performances in wide-band system.

Cooperative Orthogonal Space-Time-Frequency Block Codes over a MIMO-OFDM Frequency Selective Channel
In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...
متن کاملSingle-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
متن کاملOn the design of space-time and space-frequency codes for MIMO frequency-selective fading channels
Recently, the authors introduced an algebraic design framework for space–time coding in flat-fading channels [1]–[4]. In this correspondence, we extend this framework to design algebraic codes for multiple-input multiple-output (MIMO) frequency-selective fading channels. The proposed codes strive to optimally exploit both the spatial and frequency diversity available in the channel. We consider...

In this paper, we study the multiple-access channel where users employ space–time block codes (STBC). The problem is formulated in the context of an intersymbol interference (ISI) multiple-access channel which occurs for transmission over frequency-selective channels. The algebraic structure of the STBC is utilized to design joint interference suppression, equalization, and decoding schemes. Ea...
متن کاملSpace-time codes performance criteria and design for frequency selective fading channels
AbsrrucfThis paper studies the space-time code design for single carrier transmission over frequency selective fading channels. The design criteria are derived first and then we apply the algebraic &-rank theory proposed earlier by the authors to show how to design codes to take advantage of space and frequency diversity simultaneously. Finally, example codes are shown to achieve desired level ...
