Estimating Channel Parameters In Multi-Input, Multi-Output (Mimo) Systems

View page
US Patent:
7310304, Dec 18, 2007
Filed:
Apr 24, 2002
Appl. No.:
10/128756
Inventors:
Apurva N. Mody - Atlanta GA, US
Gordon L. Stuber - Atlanta GA, US
Assignee:
BAE Systems Information and Electronic Systems Integration Inc. - Nashua NH
International Classification:
H04J 11/00
US Classification:
370208, 370206, 370281
Abstract:
In a communication system, and in particular a wireless Orthogonal Frequency Division Multiplexing (OFDM) communication system, the present invention provides systems for estimating parameters of a channel across which a signal is transmitted. The present invention may be used in a Multi-Input, Multi-Output (MIMO) system in which the data is transmitted from any number of transmitting antennas and received by any number of receiving antennas. The number of transmitting and receiving antennas does not necessarily have to be the same. Circuitry is provided for calculating parameters indicative of the characteristics of the communication channel. Estimates of channel parameters may include channel estimates and noise variance estimates.

Time And Frequency Synchronization In Multi-Input, Multi-Output (Mimo) Systems

View page
US Patent:
7706458, Apr 27, 2010
Filed:
Jun 7, 2006
Appl. No.:
11/448395
Inventors:
Apurva N. Mody - Atlanta GA, US
Gordon L. Stuber - Atlanta GA, US
International Classification:
H04K 1/10
US Classification:
375260, 375299
Abstract:
In a communication system, and in particular a wireless Orthogonal Frequency Division Multiplexing (OFDM) communication system, the present invention provides systems for synchronizing data transmitted across a channel. The present invention may be used in a Multi-Input, Multi-Output (MIMO) system in which the data is transmitted from any number of transmitting antennas and received by any number of receiving antennas. The number of transmitting and receiving antennas does not necessarily have to be the same. Circuitry is provided for synchronizing the data in both the time domain and frequency domain. Time synchronization involves coarse time synchronization and fine time synchronization. Frequency synchronization involves coarse frequency offset estimation, fine frequency offset estimation, and frequency offset correction.

Methods And Systems For Sampling Frequency Offset Detection, Correction And Control For Mimo Ofdm Systems

View page
US Patent:
7889819, Feb 15, 2011
Filed:
Oct 6, 2003
Appl. No.:
10/680629
Inventors:
Apurva Mody - Atlanta GA, US
Gordon Stuber - Atlanta GA, US
International Classification:
H04L 27/06
H04L 27/28
H04K 1/10
US Classification:
375344, 375260
Abstract:
Methods and systems that are capable of detecting and correcting the sampling frequency offset as part of signal synchronization in MIMO OFDM systems. An exemplary MIMO OFDM system includes a transmitter with a number of OFDM modulators that provide data to antennas for transmission across a channel to a receiver. The OFDM modulators include a training symbol inserter that may insert a matrix of pilot tones into the data. The data including the matrix of pilot tones is received by a receiver having a number of OFDM demodulators including a synchronization circuit. The synchronization circuit uses the matrix of pilot tones to detect and correct the sampling frequency offset as part of the signal synchronization. The synchronization circuit may apply an open loop process including sampling frequency offset estimation, phase rotation, and channel estimation. Alternatively, the synchronization circuit may apply a closed loop process including error generation, loop filtering and accumulation as well as sampling frequency offset estimation, phase rotation, and channel estimation.

US Patent:
RE43294, Apr 3, 2012
Filed:
Sep 8, 2009
Appl. No.:
12/555332
Inventors:
Gordon L. Stuber - Atlanta GA, US
Apurva N. Mody - Lowell MA, US
Assignee:
Taffco Three Fund, L.L.C. - Wilmington DE
International Classification:
H04L 27/28
H04L 27/36
H04B 7/02
H04J 11/00
US Classification:
375260, 375267, 375299, 370208
Abstract:
Apparatus and methods for providing efficient space-time structures for preambles, pilots and data for multi-input, multi-output (MIMO) communications systems are provided. One such embodiment includes providing a computer program that includes logic configured to provide an initial structure. The computer program further includes logic configured to verify that the rows of the initial structure are linearly independent and logic configured to apply an orthonormalization procedure to the initial structure to obtain a space-time structure. Methods are also provided for providing efficient space-time structures for preambles, pilots and data for MIMO communications systems.

US Patent:
7269127, Sep 11, 2007
Filed:
Oct 4, 2002
Appl. No.:
10/264546
Inventors:
Apurva N. Mody - Atlanta GA, US
Gordon L. Stuber - Atlanta GA, US
Assignee:
BAE Systems Information and Electronic Systems Integration Inc. - Nashua NH
International Classification:
H04J 11/00
US Classification:
370210, 370430, 370482, 375144
Abstract:
A communication system is provided herein for transmitting frames across a channel. The frames may be transmitted in single-input, single-output (SISO) and/or multi-input, multi-output (MIMO) communication systems. One such frame includes at least one training symbol, each having a cyclic prefix and a training block. The time length Nof the training block is equal to an integer fraction I of the time length of a data block, i. e. , N=N/I. Furthermore, the time length G of the cyclic prefix is an integer fraction of the time length N. For example, G may be equal to N/4 or 25% of N. The training symbols provide coarse and fine time synchronization, coarse and fine frequency synchronization, channel estimation, and noise variance estimation.
