20090141869 | APPARATUS AND METHOD FOR COMPARING SIGNAL STRENGTH IN A SPEAKERPHONE SYSTEM - A method and system for comparing signal strength in a speakerphone system is disclosed. The system is configured to operate in a half-duplex mode, where the direction of communication is determined by comparing signals based on the transmit input signal and the receive input signal. The system estimates and compares the transmit data signal strength and the receive data signal strength. The system then controls a transmit switch and a receive switch to selectively enable transmission based on the comparison. The system also reconfigures the estimation components based on the comparison of the estimated signal strengths. In one implementation, the system estimates the signal envelopes for the inputs and the envelopes of the noise components of the inputs. The system uses the estimates to calculate the data component of the input signals by subtracting the noise envelope from the total signal. A controller compares the strength signals to determine the current state of the system. If one signal is stronger than the other, the controller switches to that state and blocks the weaker signal. The system uses the states to configure the system components. | 06-04-2009 |
20090303980 | APPARATUS AND METHOD FOR ERROR CONCEALMENT FOR A DIGITAL WIRELESS PHONE - A method and system to conceal transmission errors in a digital wireless system is disclosed. The system is used in the uplink or the downlink of a cordless or wireless TDMA system. When there are unused data slots available, the system allocates redundant slots in a data frame to a single mobile unit. The receiving device calculates a quality of slot (QoS) score for each slot that it receives data for. After the QoS score is calculated, the system calculates a Quality of Audio Segment (QoAS) score for each individual segment. It does so by comparing the individual audio segments that were received. Segments that are identical are assigned a positive score, while segments that differ get no score. The QoAS for each segment is added to the QoS for the slot the segment was transmitted in to generate the total score. The system then chooses the segment with the highest total score. If the total score is above a specified threshold, the system outputs the segment to the next component. Otherwise, it outputs a mute segment. | 12-10-2009 |
