  • ISDB-T Modulator
    • The CMS0045 ISDB-T Modulator provides all the necessary processing steps to modulate one, two or three transport stream into a complex I/Q signal for input to a pair of DACs, or an interpolating DAC device such as the AD9857/9957 or AD9789. Optionally the output can be selected as an IF to supply a single DAC.
    • The design has been optimised to provide excellent performance in low cost FPGA devices such as the Cyclone range from Altera or the Spartan range from Xilinx

  • Quadrature Amplitude Modulation: Modulator and Demodulator
    • 1. Quadrature amplitude modulation Aside from increased channel capacity, QAM has various other advantages, which are stated below.
    • 2. One of the most significant advantages of QAM is its ability to sustain a high data rate. As a result, the carrier signal can carry a certain amount of bits. Because of these benefits, it is preferred in wireless communication networks.
    • 3. The noise immunity of QAM is quite strong. Noise interference is a bit low as a result of this.
    • 4. It has a low mistake probability value.

  • Multi-channel Cable Modulator
    • The CMS0024 Multi-channel Cable Modulator encodes up to four separate transport streams for J83 or DVB-C.
    • The resulting QAM symbols are filtered and up-converted, each channel to its own frequency division multiplex (FDM) sub channel.
    • The IF channels are then combined output to the radio interface as a single I/Q sample stream for translation to the final RF frequency.
