Calculating obtains default BIAWGN (Binary Input Additive White Gaussian Noise, binary system Additive white Gaussian noise channel) model channel capacity, the channel capacity I (σ of BIAWGN models²) calculation formula is as follows：

Wherein, ε=1-2b,Exp () represents natural constant e= 2.71828 ... be bottom exponent arithmetic, v=(1-2b)+z, b ∈ { 0,1 }, Represent average For 0 and variance is σ²Gaussian Profile.

Step 2, when default binary additive Gaussian white noise channel model channel capacity and each polarization code transmission channel When capacity is equal, the equivalent noise variance of each polarization code transmission channel is determined.

Specifically, the channel capacity of above-mentioned default binary additive Gaussian white noise channel model and each polarization code are passed The capacity of defeated channel is equal, that is, solves equation below：

I (n, j)=I (σ²)

According to the equation, you can obtain the equivalent noise variances sigma of each polarization code transmission channel²。

By adding cyclic prefix to modulated signal, obtain sending information vector.

Polarization code coding information vector is modulated above-mentioned, obtained after modulated signal, is added before the modulated signal Cyclic prefix, obtains polarization code and encodes the transmission information vector to be formed.

It can be seen that, it can be realized by the present embodiment and compile information vector to be sent using polarization code encoding method formation polarization code Code information, is modulated to coding information by default modulation system, ultimately forms the transmission information vector of polarization code coding.

Alternatively, in a kind of embodiment of the information transferring method of the embodiment of the present invention, by polarization code coding information to Amount interweaves, and obtains the polarization code coding information vector corresponding to QAM modulation, including：

The corresponding channel of each quadrature information vector in polarization code coding information vector such as is subjected at the capacity segmentation, obtained pair Should be in the polarization code coding information vector of QAM modulation.

In embodiments of the present invention, more simplified intertexture is employed, being will be each in polarization code coding information vector The capacity segmentations such as the corresponding channel progress of quadrature information vector, obtain the polarization code coding information vector corresponding to QAM modulation.Tool Body is as follows：

In embodiments of the present invention, according to configured transmission, GFDM system channels are decomposed into JN polarization code transmission channel, Optimal deinterleaving method refers to whole JN polarization code transmission channels directly are divided into two groups, and every group has JN/2 polarization code to transmit Channel.The principle of packet is to ensure that this respective channel capacity sum of two groups of channels is equal, and the operation being so grouped is exactly Capacity is split.Then again this two groups of channels are carried out etc. with capacity segmentation respectively, by that analogy, always by waiting criterion of capacity to be grouped Go down, to the last, only two polarization code transmission channels in each group, at this moment algorithm termination.

Though optimal felt properties are good, when JN value is very big, the complexity of intertexture can be very high.

Based on " the letter of the corresponding polarization code transmission channel of same position bit in distinct symbols information in the embodiment of the present invention Road capacity is closely " this conclusion, only the segmentation of the capacity such as progress is grasped in the corresponding channel of each quadrature amplitude modulation symbols Make.The polarization code transmission channel of JN GFDM system is decomposed into 2N group (because N is quadrature amplitude modulation QAM symbols first Number number, it is contemplated that the equivalence of each qam symbol real and imaginary parts), every group includes J/2 polarization code transmission channel, Then concurrently the capacity such as this 2N polarization code transmission channel group execution are split simultaneously, you can complete to happen suddenly in sub-channel A string of bits of mistake scatter, and complete interleaving process, obtain the polarization code coding information vector corresponding to QAM modulation.

It can be seen that, in embodiments of the present invention, by interweaving each quadrature information vector in polarization code coding information vector The capacity segmentations such as corresponding channel progress, obtain the polarization code coding information vector corresponding to QAM modulation, can simplify answering for intertexture Miscellaneous degree, improves the efficiency of interleaving process.

Encoder bit rate is 0.5 and all uses CRC-24 codes in two schemes.

Fig. 6 (A) for the embodiment of the present invention GFDM system conventionals AWGN (Additive White Gaussian Noise, Additive white Gaussian noise) the Block Error Rate performance simulation comparing result figure of different modulating exponent number under transmission.In Fig. 6 (A), match somebody with somebody Put sub-carrier number K=16, subsymbol number M=8, roll-off factor α=0.1 of wave filter.The Polar QPSK of curve 1 represent to use The GFDM system curve figures of the polarization code coding of QPSK modulation, the LTE Turbo QPSK of curve 2 are represented using orthogonal The GFDM system curve figures of the Turbo codings of phase-shift keying (PSK) modulation, curve 3Polar 16QAM represent to use 16 system QAM modulations Polarization code coding GFDM system curve figures, what the LTE Turbo 16QAM of curve 4 were represented using 16 system QAM modulations The GFDM system curve figures of Turbo codings, the Polar 64QAM of curve 5 represent to encode using the polarization code of 64 system QAM modulations GFDM system curve figures, the LTE Turbo 64QAM of curve 6 represent using 64 system QAM modulations Turbo code encode GFDM system curve figures.From Fig. 6 (A), the performance of the GFDM systems of the polarization code coding of the embodiment of the present invention is compiled than Turbo GFDM 1~2dB of system of code, and performance gain increases with order of modulation J increase.

Fig. 6 (B) transmits the Block Error Rate performance simulation of lower different modulating exponent number for single footpath Rayleigh channel of the embodiment of the present invention Comparing result figure.Other configurations are constant in Fig. 6 (B), and channel is changed into single footpath Rayleigh channel.Curve a Polar QPSK represent to adopt The GFDM system curve figures for the polarization code coding modulated with QPSK, curve b LTE Turbo QPSK are represented using just The GFDM system curve figures of the Turbo code coding of phase-shift keying (PSK) modulation are handed over, curve c Polar 16QAM represent to use 16 systems The GFDM system curve figures of the polarization code coding of QAM modulation, curve d LTE Turbo 16QAM represent to adjust using 16 system QAM The GFDM system curve figures of the Turbo code coding of system, curve e Polar 64QAM represent the polarization using 64 system QAM modulations The GFDM system curve figures of code coding, curve f LTE Turbo 64QAM represent to compile using the Turbo code of 64 system QAM modulations The GFDM system curve figures of code.Simulation result now is similar with Fig. 6 (A), the polarization code coding of the embodiment of the present invention The performance of GFDM systems is better than the GFDM systems that Turbo is encoded, and performance gain increases with order of modulation J increase.
