Abstract - A paragraph that summarizes the problem and the results. In this report, we will firstly have a review of classic Multiple Access technology, TDMA, FDMA, and CDMA. Then for a higher channel ...

QAM signal constellations are supported, including QAM16, QAM64 and QAM256. QPSK, and BPSK are also supported. The operation of the demodulator is automated by a master finite state machine. The LDPC ...

The High Data Rate Demodulator IP core can demodulate BPSK, QPSK, offset-QPSK (OQPSK), 8PSK and 16QAM modulation schemes, all to a high performance level and at high symbol rates. The demodulator is ...

Speaking about modulation, in simple terms, it's the method used to impose the message signal on a carrier signal, which is then transmitted by antenna or wire. And demodulation is ... In the above ...

Abstract: In this letter, a simple method for modulation and demodulation of minimum shift keying (MSK) is proposed. It has a serial structure, and is easier to implement than the conventional ...

Abstract: It is well known that the 16-quadrature amplitude modulation (16-QAM) differently protects the bits of the same symbol. In turbo-coded transmission systems, several ways for allocating the ...
