Global IP Core rolled out the Zigbee Transceiver PHY IP Core for instant implementation. The IP Core is available for the Satellite Communication and Aerospace & Defense industry. The modulation and spreading functions for the O-QPSK PHYs are processed through 3 steps. First, each 4 bits are gathered to represent 1 symbol, which has a value from 0 to 15
Global IP Core Sales - The DVB-S2X LDPC Decoder is a powerful FEC core decoder for Digital Video Broadcasting via Satellite. It implements extensions to the DVB-S2X design for better performance and efficiency as well as robust service availability.
The Reed Solomon Encoder is fed with an input message of K information symbols, the Encoder appends 2T parity symbols to the input message in order to form the encoded codeword.
In Digital video broadcasting for cable systems systems, a powerful FEC sub-system is needed. FEC is based on LDPC (Low-Density Parity Check) codes concatenated with BCH (Bose Chaudhuri Hocquenghem) codes, allowing Quasi Error Free operation close to the Shannon limit.
The Forward Error Correction (FEC) sub-system is one of the essential basing blocks in any communication systems so a powerful FEC code is needed. The New Radio (NR) FEC for the control channel is proposed to be designed based on Polar codes allowing close to the Shannon limit/Capacity operation.
The demodulator is designed to be used together with a cable tuner and an analog to digital converter (ADC). The system has an internal state machine to control the operation, which can be externally configured via the SPI interface.
