Abstract: A configurable all-digital coherent demodulator system for spread spectrum digital communications is disclosed herein. The demodulator system includes an extended and long code demodulator (ELCD) coupled to a traffic channel demodulator (TCD) and a parameter estimator (PE). The demodulator also includes a pilot assisted correction device (PACD) that is coupled to the PE and the TCD. The ELCD provides a code-demodulated signal to the TCD and the PE. In turn, the TCD provides a demodulated output data signal to the PE. The PACD corrects the phase error of the demodulated output data based on an error estimate that is fed forward from the PE. Accumulation operations in the ELCD, TCD, and PE are all programmable. Similarly, a phase delay in the PACD is also programmable to provide synchronization with the error estimate from the PE.

Abstract: An improved visual voicemail system is provided. When a call is made to a wireless telephone device and a voicemail message is deposited for the called party, the voicemail message is transcribed to generate a text version of the deposited voicemail message. The transcribed voicemail message is sent to the called mobile telephone device to allow the user to read the text version of the voicemail message. Embedded with transcribed text voicemail message is a link that maps to a unique telephone number that is assigned to the original audio voicemail message from the text voicemail message was transcribed. If the called party selects the link, the called party's mobile telephone device or other receiving computing device places a call to the storage location of the original audio version of the voicemail message to listen to the audio version of the voicemail message.
