    摘要: A communication circuit (28) is designed with a signal processing circuit (370) arranged to produce a first plurality of data signals and receive a second plurality of data signals. A transmit circuit (364) is coupled to receive the first plurality of data signals and transmit each data signal of the first plurality of data signals on a respective transmit frequency in a predetermined sequence of transmit frequencies. A receive circuit (362) is coupled to receive each data signal of the second plurality of data signals from a remote transmitter on the respective transmit frequency in the predetermined sequence. The receive circuit applies the second plurality of data signals to the signal processing circuit.

    摘要: A communication system 100 allows for heterogeneous piconets/scattenets 100 where in multiple modes 110, 112 of transmission, one of Bluetooth 110 and one or more other modes of transmission 112 are possible. While at the same time maintaining synchronization between all the different modes of transmission 110, 112 in a given piconet and across a scatternet 100. This allows for a communication device that can communicate using a plurality of transmission modes depending on the communication needs of the device.

    摘要: Interference cancellation/suppression by a wide band radio (100) includes the steps of searching for all narrow band interferer signals such as Bluetooth signals (502). Communicating with the detected Bluetooth piconets (504). Estimating when the Bluetooth signals will occur (506) using the information received during step (504) . And using a suppression technique in association with the estimations as to when/where the interfering signals will occur in order to counter the interfering signal(s). In an alternate embodiment, both the narrow band (304) and wide band (302) signals are stored (306). Then the one or more narrow band Bluetooth signal(s) (304) and decoded (308) and subtracted (308) from the wide band packet prior to it being decoded (312).

    摘要: Space time transmit diversity (9, 14, 17, 19) is applied at the block level to an original block of bits (12) in order to reduce the effects of fading in wireless communication systems that use nonlinear modulation schemes (13, 33). At the receiving end, fading parameters (α1, α2) are estimated (αE1, αE2) and the properties of complex conjugates are utilized (28, 29, 201, 202) to produce a result (r1, r2) that is representative of the original block of bits.
