According to, and pair with the data carry out local oscillator treatment to generate local oscillation signal.
As can be seen here, for transmitting terminal, in order to pass through data, first that sef-adapting filter is produced to digital circuit
Thermal compensation signal and the second thermal compensation signal are processed, and the thermal compensation signal of mutually making an uproar needed for obtaining digital circuit, so as in digital electricity
Road the inside is accordingly compensated, so as to eliminate the influence of mutually making an uproar of transmitting terminal, analog circuit generates the first thermal compensation signal and second
Thermal compensation signal.
For the method for the suppression of mutually making an uproar according to embodiments of the present invention of receiving terminal, analog circuit can also be based on this
Before the thermal compensation signal of signal generation of shaking first, radiofrequency signal is received, and by the radiofrequency signal by low pass filter（LPF,
low pass filter）, variable gain amplifier（VGA, varied gain amplifier）And the numeral after analog-to-digital conversion
Signal is sent to the digital circuit；And local oscillator treatment is carried out to the radiofrequency signal to generate the local oscillation signal.
As can be seen here, for receiving terminal, in order to pass through data, the compensation that sef-adapting filter is produced to digital circuit
Signal is processed, and the thermal compensation signal of mutually making an uproar needed for obtaining digital circuit, accordingly to be compensated inside digital circuit,
So as to eliminate the influence of mutually making an uproar of receiving terminal, analog circuit generates the first compensation letter on the basis of the radiofrequency signal for receiving
Number.
The method that Fig. 2 shows the suppression of mutually making an uproar that digital circuit side performs, comprises the following steps：
21, digital circuit receives the first thermal compensation signal from analog circuit, and first thermal compensation signal is that data signal is entered
Fundamental frequency signal before row compensation.
22, self adaptation is carried out to first thermal compensation signal and mutually makes an uproar estimation mutually to be made an uproar.
For example, using cost function, self adaptation being carried out to first thermal compensation signal and mutually making an uproar estimation mutually to be made an uproar.
23, the phase that will be estimated makes an uproar compensation to the data signal.
Therefore, digital circuit carries out adaptive-filtering treatment by the thermal compensation signal and data signal to receiving, and produces
The estimate of mutually making an uproar of compensation needed for data signal, and accordingly compensated inside digital circuit, so as to eliminate transmitting terminal mutually make an uproar
Influence.
Further, for transmitting terminal, digital circuit can also receive the second thermal compensation signal, described the from analog circuit
Two thermal compensation signals are the fundamental frequency signals after being compensated to the data signal, and the data signal is the originally transmitted numeral
Signal after filtering with analog channel figure adjustment after generate signal；To second thermal compensation signal and originally transmitted numeral letter
Number phase difference carry out self adaptation mutually make an uproar estimation to obtain phase difference, wherein the originally transmitted data signal be coding, framing
And the data signal of mapping；And the phase difference compensation that will be estimated gives the data signal.
For receiving terminal, while the phase that will be estimated in digital circuit makes an uproar compensation to the data signal,
Also the data signal is carried out self adaptation mutually make an uproar estimation made an uproar with obtaining another phase；The described another phase that will be estimated make an uproar compensation to
The data signal.
As can be seen here, the data and thermal compensation signal for being produced to digital circuit by sef-adapting filter are processed, and are obtained
Thermal compensation signal of mutually making an uproar needed for taking digital circuit, accordingly to be compensated inside digital circuit, so that cancellation in communication systems
Influence of mutually making an uproar.
Herein, phase difference is the difference of former and later two moment instantaneous phases, and the instantaneous phase at the two moment is just
It is mutually to make an uproar.
Below, the circuit structure of the transmitting terminal and receiving terminal shown in Fig. 3 and Fig. 4 will be combined, transmitting terminal is described respectively and is connect
The method of the suppression of mutually making an uproar of receiving end.
In the circuit structure of the transmitting terminal shown in Fig. 3, the square frame in left side includes the functional module of digital circuit, right side
Square frame includes the functional module of analog circuit.
With reference to 3, digitally transmitted signals are encoded in digital circuit, framing, mapping, filtering and analog channel it is digital
After correction, into D/A converter module, so as to be converted to the data of analog signal by data signal.In general, coding is
For digitally transmitted signals to be carried out with error correction, framing is the fixed frame format of the digitally transmitted signals composition that will be encoded, for example, connect
The form that receiving end is consulted with transmitting terminal.Mapping is that the digitally transmitted signals of framing are mapped with the form for ease of sending.Filtering
It is the filtering process carried out to ensure the digitally transmitted signals of pre- transmission not disturb other signals.Analog channel figure adjustment
It is that the distortion of digitally transmitted signals in analog channel to filtered pre- transmission is corrected treatment.
The analog signal exported by D/A converter module enters in analog circuit, due to having local oscillator list in analog circuit
Unit, the local oscillation signal produced with local oscillator unit hence into the analog signal of analog circuit is overlapped mutually, and by power amplifier（PA,
power amplifier）The transmission signal for producing afterwards is launched from antenna.That is, the transmitting letter that transmitting terminal sends
Number have local oscillator composition, mutually made an uproar so as to increase.
Therefore, circuit structure as shown in Figure 3, increased some functional modules on the basis of available circuit structure respectively
（Conjugate module, Postponement module, self adaptation are mutually made an uproar estimation module, phase difference calculating module etc.）, to mutually making an uproar in transmitting terminal
Suppressed.
For example, conjugation and the module for postponing are increased in analog circuit side, so as to local oscillation signal Flo treatment.
Conjugation treatment generation conjugated signal Flo* is carried out to local oscillation signal Flo, delay disposal generation is carried out to local oscillation signal Flo and is postponed letter
Number Flo_d.Then, conjugated signal Flo* is multiplied with postpones signal Flo_d and generates the first thermal compensation signal PN_tx.

Wherein transmitting data Sig is multiplied with local oscillation signal by the data that analog circuit is input into after digital-to-analogue conversion and obtained.To transmitting data
Sig carries out conjugation treatment generation and obtains being conjugated data-signal Sig*, then will conjugation data-signal Sig* and postpones signal Flo_d
Multiplication treatment is carried out, to generate the second thermal compensation signal Sig_tx.
Specifically, data-signal Sig is：Sig=Data x Flo,
Here, local oscillation signal Flo=exp (2*pi*flo*t+ θ (t)), wherein pi are pi, and flo is local frequency, t
It is the time.
Being conjugated data-signal Sig* is：Sig*=（Data x Flo）*=Data*x Flo*,
Here, conjugated signal Flo*=exp (- 2*pi*flo*t- θ (t)), wherein pi are pi, and flo is local frequency,
T is the time；
Second thermal compensation signal Sig_tx is：Sig_tx=Sig*x Flo_d=Data*x Flo*x Flo_d=Data*x PN_
tx,
Here, postpones signal Flo_d=exp (2*pi*flo* (t-td)+θ (t-td)), the first thermal compensation signal PN_tx=
(Flo*)x Flo_d=exp(-2*pi*flo*t-θ(t))*exp(2*pi*flo*(t-td)+θ(t-td))=exp(θ(t)-θ
