Jay Gopal - Plainsboro NJ, US

Assignee:

Matsushita Electric Industrial Co., Ltd. - Osaka

International Classification:

H04L 7/00

US Classification:

375354

Abstract:

A method for generating an ultra-wide-band (UWB) having a reduced discrete frequency component defines frame synchronization signal and an inverted frame synchronization signal. As each frame is generated, the method randomly selects the frame synchronization signal or the inverted frame synchronization signal to be included with the frame. The frame synchronization signal is detected by a correlator and the magnitude of the correlation is used to indicate the detection of the frame synchronization signal.

Assignee:

Matsushita Electric Industrial Co., Ltd. - Osaka

International Classification:

H04B 1/00

US Classification:

375130, 375260

Abstract:

Methods and apparatus for generating and processing wideband signals having reduced discrete power spectral density (PSD) components are disclosed. A wideband signal having reduced discrete PSD components is achieved by generating data symbols responsive to data for transmission, transforming one or more of the data symbols into a frame including one or more orthogonal frequency division multiplexing (OFDM) symbols, selectively inverting the frame responsive to a pseudo-random data sequence, and modulating wideband signal pulses of the wideband signal with the selectively inverted frame.

Abstract:

A control method of synchronizing communications between or among a plurality of devices in a communication system includes detecting beacons from the plurality of devices in the communication system, and establishing a reservation for at least a portion of the plurality of devices in the communication system. Each reservation is a frame interval in which to transmit symbols from one device to one or more of the other devices in the communications system. Each frame interval and intra-frame interval is set according to the established reservation. Each frame interval and intra-frame interval is a plural, integral number of symbol periods in duration.

International Classification:

H03M 13/03

US Classification:

714790, 714748, 714749

Abstract:

A method of communication between or among a plurality of devices in a communication system using one or more frames to transmit a plurality of bits includes encoding the plurality of bits in accordance with a first puncture code in a first device of the plurality of devices, transmitting the plurality of encoded bits to a second device of the plurality of devices, and determining in the first device an error condition indicated in a received acknowledgement from the second device. When the error condition indicates a first error code, retransmitting the encoded bits in accordance with the first puncture code, and when the error condition indicates another error condition, different from the first error code, encoding the plurality of bits in accordance with a second puncture code, different from the first puncture code and transmitting the plurality of encoded bits to the second device.

Abstract:

Methods and apparatus for transmitting and receiving symbols in a communication system having a plurality of frequency bands are provided. A first symbol is transmitted on a first tone using a first constellation mapping and a second symbol is transmitted on a second tone using a second constellation mapping different from the first constellation mapping. The first symbol is retransmitted on the second tone using the second constellation mapping and the second symbol is retransmitted on the first tone using the first constellation mapping. The first and second symbols are detected from a combination of the received transmitted and retransmitted first and second signals.

Abstract:

Methods and apparatus for reducing discrete power spectral density (PSD) components of wideband signals transmitting blocks of data are disclosed. Discrete components are reduced by acquiring N symbols of pseudo-random data, each symbol having K bits; selecting one bit from each of the acquired symbols to generate N selected bits; selectively inverting a respective element in one of the data blocks responsive to the selected bits; acquiring one or more bits of pseudo-random data to replace a corresponding one or more respective bits of the acquired N symbols of pseudo-random data; and repeating for successive blocks of data.

Abstract:

Methods and apparatus for use in a multi-band OFDM wideband transmission systems are disclosed. A frame of source data is mapped by a transmitter for transmission using a first mapping. The frame of source data is then mapped by the transmitter for retransmission using a second mapping to increase frequency diversity. A receiver may identify source data that experiences fading and communicate the tone/frequency on which the fading occurred to the transmitter so that the transmitter may map the source data that experienced fading during transmission to another tone/frequency for retransmission.
