SAN DIEGO -- July 20, 1999 -- Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today introduced audio enhancement software technology for the MSM3000™ and MSM3100™ Mobile Station Modem (MSM™) platforms that significantly improves the already superior sound quality available to users of CDMA handsets. The PureVoice™ Audio AGC software, developed by Qualcomm CDMA Technologies, is a complete audio enhancement solution that will enable CDMA manufacturers to develop superior sounding handsets without additional hardware costs.
"Our new PureVoice Audio AGC software provides our manufacturing partners with immediate, measurable performance improvements in speech quality for their handsets," said Johan Lodenius, vice president of marketing of Qualcomm CDMA Technologies. "Implementing our software solution at the design stage ensures cost savings to manufacturers, and superior sound quality for consumers that buy their handsets."
The PureVoice Audio AGC software is a suite of highly advanced DSP algorithms performing three distinctive functions to compensate for less than ideal handset usage conditions. The forward link automatic gain control, the forward link volume control, and the reverse link limiter functions combined into a single software package provide a complete audio enhancement solution that allows for better sounding calls on CDMA handsets in adverse background noise conditions.
Forward link automatic gain control greatly enhances the speech quality of an incoming call. Wireless handset users often have difficulty finding the right sound level for inbound calls due to variations in the land side speaker's voice loudness, variations in loudness of automated voice-mail recordings, and loudness variations in analog phone and landline signals. PureVoice Audio AGC software minimizes these effects by dynamically tracking changes in the forward link audio signal and normalizing output gain levels, thus providing an ideal audio output gain level in a variety of conditions.
The software's forward link automatic volume control tracks the background noise levels in the user's operating environment and automatically adjusts the volume level best suited for the situation. By dynamically adding up to a +24dB digital gain to the handset volume level, handset users can still experience call clarity regardless of background noise levels without manually adjusting the volume control. This feature makes wireless handsets more convenient to use.
The reverse link limiter (RLL), another important feature of PureVoice Audio AGC, can make a handset sound better to landline listeners for wireless calls made under noisy conditions. The natural reaction for wireless callers in loud settings is to "talk over" background noise. This situation results in clipping and over saturation, common side effects that degrade the overall voice quality of the caller. PureVoice Audio AGC's RLL compensates for this scenario without affecting normal input volume levels. RLL prevents clipping and over saturation of the handset's audio signal to ensure call clarity.
Qualcomm's PureVoice Audio AGC software is optimized for both the MSM3000 and MSM3100 platforms and will be available for the MSM3000 in Q4 1999. The industry-leading MSM3000 is the only currently available hardware and software solution to support IS-95B with data rates up to 86.4kbps and to provide 200 hours of standby time. Qualcomm's sixth-generation, the MSM3100 chipset and system software will sample in the third quarter of 1999.
