About spectralDSP

The company was founded to solve the inefficient OFDM PAPR (Peak-To-Average-Power-Ratio) energy usage issues bedeviling the Telecom /ITC world for over 30 years. The cellular network was built for a signal spike but the vast majority of time you are utilizing the channel at much lower (power). We solve that!

The result was a mathematical /wave form modulation solution in software that allows the respective Power Amplifier chips to operate at 3dB to more than 9dB improvement all with the same input power to the Power Amplifier Chips.
This results in up to 16X less power requirement by the Power Amplifier Chip and saves 25% to over 50% of the needed input power for the transmission at maximum allow limits at the antenna.
This sDSP UltraWave technology initial implementation was proven on the FCC COSMOS Test bed in NYC during June 2021

SpectralDSP's Solutions

OFDM PAPR Power Consumption Reduction

The UltraWave technology is designed to be used in virtually any multichannel RF environment with the same options for improvement. It is spectrum agnostic.

The UltraWave technology will be used in both base station and Handsets/ UE with software uploads. New equipment will have the benefit of less expensive/ smaller Power Amplifier Chips, as they will not need to higher wattage to produce maximum range from the antenna.

* The UltraWave technology will also have positive effect on the battery life of battery transmission usage in the handsets (not getting hot when talking a long time and battery lasting 16%-27% longer).

NEXTG ALLIANCE

The Next G Alliance is a bold new initiative to advance North American mobile technology leadership over the next decade through private sector-led efforts. With a strong emphasis on technology commercialization, the work will encompass the full lifecycle of research and development, manufacturing, standardization and market readiness. Ensuring North American leadership in mobile technology.

IEEE SPECTRUM

5G has a power efficiency problem. But now there is a solution to the PAPR problem. Start-up Spectral DSP has developed and tested a variation on OFDM signals that will significantly lower PAPR. It is called UltraWave. Implementing this new technique in wireless networks would greatly reduce the cost of 5G deployments and extend the battery lives of 5G-enabled smartphones.

SPECTRALDSP BREAKTHROUGH

spectralDSP Announces a Breakthrough in Waveform Technologies. Deployment of TRUE 5G mmWave Gigabit Speeds and Low Latency will finally be Cost-effective. Our solution can be rolled out via simple reprogramming of cellular modem software. spectralDSP’s proprietary waveform modulation technique is at the heart of the solution. spectralDSP technology reduces PAPR.
