Abstract: Un dispositif et un procédé utilisent une configuration retour/anticipation linéaire afin d'estimer et de supprimer l'écho d'un récepteur, dans laquelle un égaliseur (202) et des unités (204 et 208) de suppression d'écho du récepteur sont conjointement mises à jour, ce qui permet la détermination d'un signal d'erreur une fois (204 et 208), à la place du procédé antérieur de détermination de signal d'erreur séparé pour un égaliseur et un suppresseur d'écho de récepteur. On utilise une technique améliorée de correction de phase afin de compenser le décalage de fréquence dans l'écho du récepteur. La relation entre l'écho du récepteur et l'écho distant de l'émetteur est utilisée afin de faciliter la suppression de l'écho du récepteur.

Abstract: A method of determining a rate associated with a received signal including the steps of detecting the received signal (40); decoding (42) the received signal at a first rate, determining a first path metric associated with the first rate (44), decoding (42) the received signal at a second rate, and determining a second path metric associated with the second rate (44); calculating a plurality of discriminant functions based on the first and second path metrics (46); comparing at least one of the plurality of discriminant functions to a predetermined value (48); and selecting one of the first and second rates as a determined rate based on the comparison (62, 66, 72, and 78).

Abstract: The method includes acquiring a signal (501); inputting (502), at a first time, a received symbol to a demodulator having a plurality of outputs to produce a set of early outputs; inputting (504), at a second time, the received symbol to the demodulator to produce a set of on-time outputs; inputting (505), at a third time, the received symbol to the demodulator to produce a set of late outputs; and comparing (506) at least one output in the set of early outputs with at least one output in the set of late outputs to produce a timing measure.

Abstract: A method of adjusting a power control setpoint threshold (216) in a wireless communication system is provided. The method includes the steps of receiving at a receiver, a communication signal from a mobile communication unit to form a received communication signal, generating a first signal quality indicator (193) based on the received communication signal, generating a second signal quality indicator (194) based on the received communication signal, and generating an estimated signal-to-noise ratio (98). The method further includes setting a predetermined reference region (605) centered around a second signal quality indicator reference (206) where the second signal quality indicator reference (206) is related to the first signal quality indicator (193), and adjusting the power control setpoint threshold (216) based on a comparison between the second quality indicator (194) and the predetermined reference region (605).
