In this paper, we present a new outage probability analysis of a cooperative system with single antenna terminal. We first introduce the cooperation protocol of the presented scheme. Then, in the destination node, maximal ratio receiver combining (MRRC) and the maximum likelihood (ML) detection algorithm are applied to decode the received signal with the utilization of the signal received from the...
In this paper, we present a low complexity maximum likelihood (ML) detection based on the sphere decoder (SD) for distributed time-reversal space-time block code (D-TR-STBC) with frequency selective fading links. Unlike direct transmission, the relay-assisted transmission results in higher number of taps for the resultant end-end channel. The complexity of Viterbi algorithm (VA) grows exponentially...
In this paper we evaluate the performance of a multi stage receiver for coded signals (using space time block codes) when MIMO (multi input multi output) channels are employed. This provides a new paradigm for transmission over Rayleigh fading channels where scattering phenomenon is a major obstruction. At the transmitter side data encoded using a space-time block code, and the encoded data is split...
A fast maximum-likelihood (ML) detection scheme is proposed for the important quasi-orthogonal space-time block codes (STBCs) of symbol rate 2 for three and four transmission antennas. In particular, the proposed scheme is applicable even to the under-determined system where the number of transmission antennas is larger than that of the receive antennas. The half of the symbols of the transmission...
A new construction of a full-diversity full-rate space-time block code (FDFR-STBC) is presented in this paper. The design is for 2 transmit antennas and 2 time slots. The code outperforms the previous FDFR-STBC codes in [3], [4], [5], [6] for 1 receive antenna. We reduce the decoding complexity by exploiting the algebraic structure of the code and using the hybrid maximum-likelihood interference cancellation...
