Appl. No.:

09/820963

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H04K 1/00

US Classification:

375148

Abstract:

Interference cancellation is performed in a communication system. A signal associated with the users is received to produce a received signal. A set of regeneration factors associated with the users is determined based on the received signal. A frequency range associated with a first user from the users has at least a portion overlapping with at least a portion of a frequency range associated with a second user from the users. A time range associated with the first user from the users has at least a portion overlapping with at least a portion of a time range associated with the second user from the users. A regenerated signal associated with each user from the users is modified based on the determined regenerated factor associated with that user to produce a modified regenerated signal for each user.

US Classification:

342057000, 342060000, 342120000

Abstract:

A method and system are disclosed where transmitted radar pulses are utilized for both a radar sensing function and for data communications. The data communications are performed in a manner that is simultaneous and transparent to the radar sensing function, in terms of non interference or interruption. The method and system are applicable to data communications between multiple pulsed radar devices as well as radar devices that are capable of receiving pulsed transmissions and transmitting continuous wave transmissions.

Abstract:

A system and method for performing initial synchronization during wireless sector searches. The system includes a first subsystem for coarse timing alignment including a decimator to reduce computational complexity and a long-lag differential correlator, a second subsystem for jointly estimating RTE and FFO utilizing a short-lag differential correlator, and a third subsystem for jointly detecting IFO and SID utilizing segmental FD MFs. The system and method of the present disclosure accounts for intercell interference, ICI, and multipath fading with assistance from inherent diversity.

International Classification:

H04L 25/02

H04L 5/00

Abstract:

A system and method for disintegrated channel estimation in wireless networks. The system provides a disintegrated channel estimation technique required to accomplish the spatial diversity supported by cooperative relays. The system includes a filter-and-forward (FF) relaying method with superimposed training sequences for separately estimating the backhaul and the access channels. To reduce inter-relay interference, a generalized filtering technique is provided which multiplexes the superimposed training sequences from different relays to the destination by time-division multiplexing (TDM), frequency-division multiplexing (FDM) and code-division multiplexing (CDM) methods.

Abstract:

A receiver configured to receive wave packets encoded with data via a nonlinear channel is disclosed. The receiver includes an input configured to receive the wave packets from the non-linear channel. The receiver also includes a processor configured to generate a transfer matrix from the received wave packets and find the representation of the transfer matrix as ratios of polynomials and compute the non-linear Fourier spectrum in which the data has been embedded. The receiver may also include a demodulator configured to demodulate the non-linear Fourier spectrum to recover the data. Periodic boundary conditions may be selected. Boundary conditions may be selected based on a non-periodic vanishing signal. The received wave packets may be configured as solitons. The nonlinear channel may be an optical channel.
