    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.

    摘要: An equalization technique for an ADSL data communications system is disclosed. The effective channel overall response is made a window of length I equal to the length of the cyclic prefix. The response energy output of filtering is monitored against a preset threshold value to adaptively position the window.
