Page 264: Harmonic Distortion And Spectrum Purity
Annex Annex A Terminology Harmonic distortion and spectrum purity The ideal sine wave shall be of a single frequency. Since the non-linear element in the signal generator causes non - linear distortion and harmonic components of the signal, the signal distortion is generally used to represent the degree of the signal closing to the ideal sine wave, which is expressed with the distortion factor γ: Where, U1 is the valid fundamental wave value, U2,U3,…...
Page 265: Channel Coding
Annex Annex A Terminology dramatically the transmission code rate, with extremely high bandwidth efficiency. However, it is limited by the feature extraction algorithm, with certain intelligibility but poor naturalness. Hybrid coding, such as integrated waveform coding and parameter coding, which lowers the code rate and improves naturalness of the synthetic audio, being the source coding method widely adopted in the wireless communication field, Such as the RPE-LTP algorithm and CELP algorithm adopted in the GSM and CDMA system respectively.
Page 266: Bandwidth Efficiency Of Digital Modulation Signal
Annex Annex A Terminology baseband signal output from the low pass filter that is not subject to regeneration after modulation, and bit timing is adopted on the oscilloscope as the waveform for repeated sweep display during external synchronization. Bandwidth efficiency of digital modulation signal It is the information data transmission rate, but independent of the modulation type.
Page 267: Quadrature Phase Shift Keying Qpsk
Annex Annex A Terminology Fig. 2 Schematic diagram of BPSK Quadrature phase shift keying QPSK The most common digital modulation type is the quadrature phase shift keying. Quadrature phase shift modulation is to represent the input digital information via the four different phase differences of the carrier, and the four carrier phases are 45º, 135º, 225º...
Page 268: Quadrature Amplitude Modulation Qam
Annex Annex A Terminology Fig. 4 Schematic diagram of 8PSK Quadrature amplitude modulation QAM QAM is to conduct suppress carrier double - band amplitude modulation on two mutually-orthogonal carriers with the same frequency via two independent baseband signals, so as to realize transmission of two-channel concurrent digital information.
Page 269: Qpsk Modulation Type
Annex Annex A Terminology with an offset of 45º are used, each symbol is always subject to phase change, avoiding the 180º phase change and preventing the vector trace from passing through the zero point. Fig. 7 Combined constellation QPSK modulation type The I and Q bit streams of QPSK modulation are conversed at the same time, that is, the symbol clocks of such two paths are provided synchronously.

Annex Annex A Terminology 2Δf is a half of the code element rate, which is called the min. frequency shift keying (MSK) . 1 Bit for each symbol Figure 9 MSK modulation type 3π/8 rotation 8PSK modulation（EDGE） 3π/8 rotation 8PSK modulation is the digital modulation type used in the EDGE system. EDGE system is the upgraded GSM technique developed in Europe, which is mainly used for improving the air interface transmission rate of the GSM system.
Page 271: Nyquist Filter Factor Α
Annex Annex A Terminology RS. In other words, such Nyquist filter can limit the signal bandwidth while eliminating interference between symbols. As shown in the figure, the symbol energy of the time domain impulse response of the raised cosine filter complying with the Nyquist principle at the time of t of adjacent bits is 0, without any interference between symbols.
