radioSOFT 1.0

A radioSOFT 1.0 set with an all-inclusive software repertoire can be used in any mode, anywhere in the world. Changing the service type, the mode, and/or the modulation protocol involves simply selecting and launching the requisite computer program, and making sure the batteries are adequately charged if portable operation is contemplated.

• radioSOFT 1.0 is next generation poartable radio system providing secure & reliable, voice & data communications for mobile military and amateur users.
• Supports the HF frequency from 1.8 MHz to 65.0 MHz & the VHF frequency range from 135.0 to 185.0 MHz.
• Allows recieve & transmit in all modulation schemes viz. SSB, AM, FM, CW and Digital Data.
• Dynamically compute the required filters. Provides Automatic notch filter, noise reduction, noise blanker and sqletch etc.
• Supports 3/10-band Euqalizer and the Multi-Receive capabilities to demodulate two different signals in the same passband.
• Provides 128 bits AES (Advanced Encryption Standard).

The most significant asset of radioSOFT 1.0 is versatility. The wireless systems employ protocols that vary from one service to another. Even in the same type of service, for example wireless fax, the protocol often differs from country to country.

The radioSOFT HW consists of a receiver and/or a transmitter, where each has the following properties, respectively:
(a) the received signal is digitized and then processed using software-programmable digital signal processing techniques (digitization may occur at the rf, IF, or baseband);
(b) the modulated signal to be transmitted is generated as a digital signal using software-programmable digital signal processing techniques; the digital signal is then converted to an analog signal for transmission (the conversion to analog may occur at baseband, IF, or rf); and
(c) a key element of these radios is that software programmability allows easy changes of the radio's fundamental characteristics such as modulation types, operating frequencies, bandwidths, multiple access schemes, source and channel coding /decoding methods, frequency spreading/despreading techniques and encryption/decryption algorithms.
