چکیده
We design pilot symbol assisted modulation for carrier frequency offset (CFO) and channel estimation in orthogonal frequency division multiplexing (OFDM) transmissions over multi-input multi-output (MIMO) frequency-selective fading channels. By separating CFO and channel estimation from symbol detection, the novel training patterns lead to low-complexity CFO and channel estimators. The performance of our algorithms is investigated analytically, and then compared with an existing approach by simulations.

Rate-one Space Frequency Block Codes with Maximum Diversity Gain for MIMO-OFDM - Global Telecommunications Conference, 2003. GLOBECOM '03. IEEE
We proposed a novel rate-1, space-frequency (SF) code for an Orthogonal Frequencey Division Multiplexing (OFDM) system with transmit (M ) and receive (N ) antennas that achieves the maximum diversity attainable over frequencyselective channels. Since the SF code symbol is transmitted in one OFDM block duration, it has smaller processing delay than previously proposed Space-Time-Frequency (STF) ...
متن کاملA Multi-Antenna Detection Algorithm for UMTS/TDD Receivers in Strong Interference Environments - Global Telecommunications Conference, 2003. GLOBECOM '03. IEEE
We propose a space-time detection algorithm for a UMTS/TDD downlink scenario with strong interference. Conventional space-time detection schemes based on MMSE equalization require accurate estimation of the correlation matrix of the received signal vector, which is difficult because of the time variation of the mobile radio channel. We thus develop a decision feedback detection scheme in which ...
متن کاملBlind Coarse Timing Offset Estimation for CP-OFDM and ZP-OFDM Transmission over Frequency Selective Channels
We present a blind coarse timing offset estimation technique for CP-OFDM and ZP-OFDM transmission over frequency selective channels. The technique exploits the cyclic prefix or zero padding structure to estimate the starting position of the OFDM symbols without requiring any additional pilots. Simulation results are performed on various channel models with timing and frequency offsets. The pres...
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...
متن کاملTransmission subspace tracking for MIMO communications systems - Global Telecommunications Conference, 2001. GLOBECOM '01. IEEE
This paper describes the benefits of transmission subspace tracking for multiple input multiple output communications systems, and applies the concepts of previous work on adaptive transmit antenna algorithms to this problem. A specific stochastic gradient technique of subspace or “multi-mode” tracking of the independent modes of the MIMO transfer function and the application to space time codi...
