FSK Modulation in VHDL . Hello, I have a VHDL block that performs FSK modulation. It looks like this. The operation of the VHDL block goes like this. Fsk_data selects Fsk_u or Fsk_l depending upon its bit value( either 0 or 1). The Logik block decides which bit of fsk_data to be used to set this multiplexer.

The communication profile described by the IEC 61334-5-1 standard is based on the S-FSK modulation technique. S-FSK is a modulation and demodulation technique which combines some of the advantages of a classical spread spectrum system (e.g., immunity against narrowband interferers) with the advantages of a classical FSK system (low-complexity, well-investigated implementations). The bandwidth efficiency of this coded M-ary FSK scheme is defined by 2 2 M log C B b ρ = = . (5) To maximize the efficiency, we have to find the largest |C| for a given M and d min. It is easy to see that for a code with code words of length M each having M different numbers d min is always ≥ 2. The cardinality |C| of this code is M!. A noncoherent two-way relaying system is developed using physical-layer network coding for improved throughput over conventional relaying in a fading channel. Energy-efficient noncoherent operation is achieved using multitone frequency shift keying (FSK). A novel soft-output demodulator is developed for the relay, and corresponding achievable exchange rates are found for Rayleigh fading and ...

Jun 23, 2015 · Quadrature signals, also called IQ signals, IQ data or IQ samples, are often used in RF applications. They form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. This post looks at the concept of IQ signals and how they are used. M-ary-FSK (MFSK), M-ary-PSK (MPSK) Modes on the HF bands utilize frequency or phase modulation of a sub-carrier, which then in turn modulates a carrier using suppressed carrier SSB keying, or by directly modulating a carrier. Decoding can be done from the receiver AF or IF output (USB, LSB, CW or FAX demodulator).
