چکیده

A study of space-time block coding in analytical form-multiple input and multiple output (STBC-MIMO) system was done in various cases. Initially, a basic Alamouti scheme for encoding was illustrated. Then, the performance of proposed STBC-MIMO was studied under varying a number of transmitting antennas, varying number of receiving antennas, varying channels, various modulations and also at varying rates. The simulation results were obtained for all cases. At each and every stage, a new encoding matrix was derived.

Single-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...

Matrix Form Lapped Space Time Block Coding in Frequency Selective Channels

Space-Time Block Coding (STBC) is first introduced for quasi-static flat-fading channels by Alamouti. This paper proposes a modified delayed version of STBC for frequencyselective channels called Lapped Matrix STBC (LM-STBC), by introducing at least a delay of the order of the number of channel taps. This scheme uses two transmit antennas and one or multiple receive antennas and is applicable t...

Turbo coded HSDPA systems with transmit diversity over frequency selective fading channels

Transmit diversity is one of the key contributions to the 3G (third generation) WCDMA (wide-band code division multiple access) systems to accommodate high data-rate applications, where spatial diversity is introduced into the signal by transmitting through multiple antennas. While turbo codes are well understood to be able to provide powerful error correction ability in a SISO (single input si...

Frequency-Domain Space-Time Block Coded-Joint Transmit/Receive Diversity for Direct-Sequence Spread Spectrum Signal Transmission

Recently, we proposed space-time block coded-joint transmit/receive antenna diversity (STBC-JTRD) for narrow band transmission in a frequency-nonselective fading channel; it allows an arbitrary number of transmit antennas while limiting the number of receive antennas to 4. In this paper, we extend STBC-JTRD to the case of frequency-selective fading channels and propose frequency-domain STBC-JTR...

Comparison of BER for BPSK & QAM modulation with Alamouti STBC

On comparing the error performance of various space-time block codes(STBC) for the quasi-static Rayleigh fading channels and with different modulation techniques as BPSK,QAM, it is observed that the slope of BER is steepening as Eb/N0 is increased. It is also observed that a higherorder diversity is obtained with a larger number of transmit antennas, that is, steepening the slope of BER curves ...
