US Patent:

6487259, Nov 26, 2002

Filed:

Aug 24, 1999

Appl. No.:

09/382170

Inventors:

David William Russo - Woodinville WA

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H03D 100

US Classification:

375341, 714792, 375349

Abstract:

The partially-parallel trellis decoder with equalizer ( ) uses multiple channel estimators ( ) but less than one independent channel estimator for each state. The state information set from the state with the best state metric as computed during the previous time period is used to update a primary channel estimator ( ), and a state information set from the state with the second best state metric as computed during the previous time period is used to update a secondary channel estimator ( ). Each updated channel estimator ( ) processes the corresponding state information set to calculate the possible transmitted symbols and their associated state metrics. Because there are fewer channel estimators than states, any unassigned states are processed using the primary channel estimator ( ) but do not update the primary channel estimator ( ).

International Classification:

G08C 15/00

US Classification:

370252, 370347, 370465

Abstract:

Embodiments include a system and method for solving a wireless communications channel packing problem by using a cost-like accounting metric that includes channel packing efficiency as well as modulation efficiency, channel conditions and or noise thresholds. The cost-like accounting metric is used to adjust the rated effectiveness of using each available modulation scheme where modulation schemes in adjacent spectrum will produce differing degrees of packing efficiency. By selecting those available carrier wave modulation schemes based on channel conditions versus noise threshold and accounting for packing factor as well as modulation efficiency, some embodiments the invention achieve higher quality within the framework of creating the greatest overall channel efficiency by selecting the best modulation scheme for each part of the spectrum being used.

International Classification:

US Classification:

370338, 370334, 370352, 4555621, 455418, 343702

Abstract:

A wireless device is coupled to a multi-sector antenna that includes a plurality of different sectors, any of which can be activated to transmit and receive in a desired direction specific to that sector. Optionally, an omnidirectional antenna is included for initially establishing a wireless connection with another wireless device, such as an access point. A parameter indicative of signal quality, such as throughput or received signal strength indication (RSSI) is determined by polling with each antenna sector to establish a prioritized candidate list. If a receive Trigger becomes active in response to a parameter falling below a threshold level, a new candidate sector is selected from the current list based upon a next-best signal quality. The directionality of the multi-sector antenna provides a substantially higher data rate compared to that of the conventional omnidirectional antenna.

US Classification:

455 661, 4555521, 455 633, 375132

Abstract:

A system and method for preventing a wireless controller system and WiFi radio system within a console from interfering with each other. The WiFi system is prevented from activating its transmitter during the controller receive times by detecting a signal sent to the WiFi module indicating where the controller receive times occur. Based upon the state of the signal, the WiFi transmission algorithm can determine the appropriate times to turn on and off the WiFi transmitter in concert with the defined 802. 11 media access protocol. Furthermore, the WiFi module provides its operating channel information to the controller radio system to avoid using the WiFi channel for any communications.

Inventors:

Gregory Ray Smith - Bellevue WA, US
David Russo - Woodinville WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G10L 21/02

US Classification:

704228, 704270

Abstract:

An audio processing system includes a voice decoder and an audio processor. In one exemplary embodiment, the audio processing system is embedded in a headset unit that is wirelessly coupled to a game console. The voice decoder is used to decode a stream of incoming voice data packets carried over a wireless signal. The decoded voice data packets are used to drive an audio transducer of the headset unit. Upon detection of an error in the incoming stream, a decoded error-free voice data packet that has been stored in a replay buffer is used to generate an amplitude scaled audio signal. The voice decoder is disconnected from the audio transducer and the scaled audio signal is used to drive the audio transducer instead.

Abstract:

An accessory is provided wireless connectivity with a game console by reconfiguring an earlier transport format that was used to solely transport voice data packets. The reconfiguration incorporates the use of a hybrid sub-frame, wherein voice data packets are replaced with communication data packets. The replacement is indicated by a set of identification bits inserted into a payload identifier field of the hybrid sub-frame.
