“…SFBC formance gain for a practical system remains difficult due to the unknown channel statistics. Analytical results, however, are available for coded OFDM systems operating over channels with specific distortion and known fading distribution [14], [23], [24], [25]. SFBC-ECC refers to the case in which error correction coding is exploited by the receiver to improve the reliability of decisions used for adaptive channel estimation.…”

Alamouti space-frequency block coding, applied over the carriers of an OFDM system, is considered for obtaining transmit diversity in an underwater acoustic channel. This technique relies on the assumptions that there is sufficient spatial diversity between the channels of the two transmitters, and that each channel changes slowly over the carriers, thus satisfying the basic Alamouti coherence requirement and allowing simple data detection. We propose an adaptive channel estimation method based on Doppler prediction and time-smoothing, whose decision-directed operation allows for reduction in the pilot overhead. System performance is demonstrated using real data transmitted in the 10-15 kHz acoustic band from a vehicle moving at 0.5-2 m/s and received over a shallow water channel, using QPSK and a varying number of carriers ranging from 64 to 1024. Results demonstrate an average mean squared error gain of about 2 dB as compared to the single-transmitter case and an order of magnitude decrease in the bit error rate when the number of carriers is chosen optimally.

Timing and carrier synchronization is a fundamental requirement for any wireless communication system to work properly. Timing synchronization is the process by which a receiver node determines the correct instants of time at which to sample the incoming signal. Carrier synchronization is the process by which a receiver adapts the frequency and phase of its local carrier oscillator with those of the received signal. In this paper, we survey the literature over the last 5 years (2010)(2011)(2012)(2013)(2014) and present a comprehensive literature review and classification of the recent research progress in achieving timing and carrier synchronization in single-input single-output (SISO), multiple-input multiple-output (MIMO), cooperative relaying, and multiuser/multicell interference networks. Considering both single-carrier and multi-carrier communication systems, we survey and categorize the timing and carrier synchronization techniques proposed for the different communication systems focusing on the system model assumptions for synchronization, the synchronization challenges, and the state-of-the-art synchronization solutions and their limitations. Finally, we envision some future research directions.

In this paper, we consider CFO to be random, which gives us a more practical approach to detector design.…”

In this paper we propose a new detection scheme for spacetime block coded (STBC) systems over a flat Rayleigh fading channel. A detector is derived for a receiver having unknown channel state information (CSI) and carrier frequency offset (CFO). The proposed detector is based on a linear minimum mean square error (MMSE) symbol estimator. Analysis of the relative performance of the proposed detector with the conventional method is done by simulation for different modulation schemes and in the presence of multiple estimation error variances. It is shown that the proposed detector outperforms the conventional detector in terms of bit error rate (BER).
