nk::comm::modnorm
Value modnorm(const Value &ref, const std::string &type, double target, std::pmr::memory_resource *mr=nullptr)
Constellation normalisation factor (factor = modnorm(ref, type, target)).
nk::comm::pammod
Value pammod(const Value &x, int M, double ini_phase, const std::string &symbol_order, std::pmr::memory_resource *mr=nullptr)
M-ary PAM modulator (y = pammod(x, M, ini_phase, symbol_order)).
nk::comm::qamdemod
Value qamdemod(const Value &y, int M, const std::string &symbol_order, bool unit_power, std::pmr::memory_resource *mr=nullptr)
Rectangular M-ary QAM demodulator (x = qamdemod(y, M, symbol_order, unit_power)).
nk::comm::pamdemod
Value pamdemod(const Value &y, int M, double ini_phase, const std::string &symbol_order, std::pmr::memory_resource *mr=nullptr)
M-ary PAM demodulator — nearest-amplitude decision (x = pamdemod(y, M, ini_phase, symbol_order)).
nk::comm::qammod
