Space Frequency Coded Ofdm
We are going to implement and study a space frequency coded OFDM system which consists of two transmitters and a single receiver. Simple Alamouti spacetime code is used. An M-ary PSK modulation is used to modulate the symbols across an OFDM channel. We will also propose a variation of the scheme which tries to spread additional symbols across time-frequency attempting to increase the rate of tr...
متن کاملMultilayered Space-Frequency Block Coded OFDM Systems
In this paper, we propose a multilayered spacefrequency block coded OFDM system, which is a combination of the vertical layered space-time architecture, known as V-BLAST, and the space-frequency block coded OFDM system. This system is designed to provide reliable as well as very high data rate communications over frequency-selective fading channels with low decoding complexity. Orthogonal Frequ...
متن کاملSpace-frequency coded broadband OFDM systems
Space-time coding for fading channels is a communication technique that realizes the diversity benefits of multiple transmit antennas. Previous work in this area has focused on the narrowband flat fading case where spatial diversity only is available. In this paper, we investigate the use of space-time coding in OFDMbased broadband systems where both spatial and frequency diversity are availabl...
متن کاملA rate-one non-orthogonal space-time coded OFDM system with estimation for frequency selective channels
In this paper, we investigate the impact of applying the channel estimation method in [I] to an OFDM system quipped with rate 1 non-orthogonal space time block code[Z] for K transmit and 1 receive antenna. A new training pattern based on the Hadamard construction is designed that enables estimation of the K channels separately and thus reduces the effective noise variance in the estimate. The s...
متن کاملSpace-frequency coded MIMO-OFDM with variable multiplexing-diversity tradeoff
Space-frequency coded Orthogonal Frequency Division Multiplexing (OFDM) is capable of realizing both spatial and frequency-diversity gains in multipath multiple-input multipleoutput (MIMO) fading channels. This naturally leads to the question of variable allocation of the channel’s degrees of freedom to multiplexing and diversity transmission modes. In this paper, we provide a systematic method...
