OFDM Communications over Time-Varying Channels
Orthogonal frequency-division multiplexing (OFDM), also known as multicarrier modulation (Bingham, 1990; Cimini Jr, 1985; Keller & Hanzo, 2000; Le Floch, Alard, & Berrou, 1995; Sari, Karam, & Jeanclaude, 1995; Wang & Giannakis, 2000; Zou & Wu, 1995), relies on the concept of parallel data transmission in the frequency domain and mainly owes its success to the easy equalization for linear time-i...
متن کاملLayered turbo space-time coded MIMO-OFDM systems for time varying channels
A joint detection-estimation scheme is proposed for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. The transmitter employs a layered turbo space-time code. The iterative scheme proposed for the receiver integrates in one scheme turbo decoding, coantenna nterference suppression and channel estimation. A main observation is that the high coding gain...

The MIMO techniques with OFDM is regarded as a promising solution for increasing data rates, for wireless access qualities of future wireless local area networks, fourth generation wireless communication systems, and for high capacity, as well as better performance. Hence as part of continued research, in this paper an attempt is made to carry out modelling, analysis, channel matrix estimation,...
متن کاملRobust Adaptive OFDM with Diversity for Time-Varying Channels
The performance of an orthogonal frequency-division multiplexing (OFDM) system can be significantly increased by using adaptive modulation and transmit diversity. An accurate estimate of the channel, however, is required at the transmitter to realize this benefit. Due to the time-varying nature of the channel, this estimate may be outdated by the time it is used for detection. This results in a...
متن کاملLow-Complexity ICI Cancellation in Frequency Domain for OFDM Systems in Time-Varying Multipath Channels
In this letter, we propose a partial minimum mean-squared error (MMSE) with successive interference cancellation (PMMSESIC) method in frequency domain to mitigate ICI caused by channel variation. Each detection, the proposed method detects the symbol with the largest received signal-to-interference-plus-noise ratio (SINR) among all the undetected symbols, using an MMSE detector that considers o...
