Space-time Block Codes (stbc) for 4 Transmit Antennas
نویسنده
چکیده
In modern wireless communications, numerous diversity techniques are used to improve the performance of signal transmission over multiple channels. This paper focuses primarily on the evaluation of Quasi Orthogonal & Orthogonal Space-Time Block Codes (STBC) for a 4x2 system model. The paper proceeds by checking which of these two codes Orthogonal STBC or Quasi-orthogonal STBC, is better by evaluating relationship between the Symbol Error Rate (SER) and Signal to Noise Ratio (SNR). Furthermore we shall evaluate the performance of each with respect to their diversity.

Frequency-Domain Receivers for Rate-1 Space-Time Block Codes
This paper considers iterative frequency-domain receivers for block transmission techniques with rate-1 Space Time Block Coding (STBC) for two and four transmit antennas using both Orthogonal Frequency Division Multiplexing (OFDM) and Single-Carrier (SC) schemes. The proposed receiver includes an interference canceller which enhances the performance of the non-orthogonal STBC scheme with 4 tran...

In this paper, we deal with the design of high-rate, full-diversity, low maximum likelihood (ML) decoding complexity space-time block codes (STBCs) with code rates of 2 and 1.5 complex symbols per channel use for multiple-input multiple output (MIMO) systems employing three and four transmit antennas. We fill the empty slots of the existing STBCs from CIODs in their transmission matrices by add...
متن کاملComparison 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 ...

Transmit diversity schemes for the coherent multiple-antenna flat-fading channel range from spacetime block codes (STBC) to space-time trellis codes (STTC). In this letter we compare the performance of STBC and STTC by means of frame error rate. We discover that a simple concatenation of STBC with traditional AWGN (additive white Gaussian noise) trellis codes outperforms some of the best known ...
