Wherein, acquisition module 201 is specifically as follows mike, and output module 203 is specifically as follows speaker.Acquisition module
201 Real-time Collection ambient sounds obtain analoging sound signal, and analoging sound signal is converted to into the first raw tone (numeral letter
Number), sample rate can be 8kHz, and data bit length can be 16Bit, data transfer rate 128kbps.Output module 203 is original by second
Voice (digital signal) is converted to analoging sound signal and plays out, data transfer rate 128kbps.
In embodiments of the present invention, processing module 102 can adopt various different algorithm realities when voice coding is carried out
Existing, for example, processing module 102 can be used for former to first using enhancement mode MELP algorithm (MELPe algorithms)
Beginning voice is encoded.
In embodiments of the present invention, processing module 102 can be used for for first raw tone of 67.5ms adopting 1.2kbps
Speech encoding rate be encoded to the block of speech of 88bit (11 bytes), the block of speech of 88bit include the data bit of 81bit and
The control bit of 7bit；Or, first raw tone of 90ms is encoded to into 56bit (7 using the speech encoding rate of 0.6kbps
Individual byte) block of speech, the block of speech of 56bit includes the data bit of 54bit and the control bit of 2bit；Or, by 22.5ms's
First raw tone is encoded to the block of speech of 56bit using the speech encoding rate of 2.4kbps, and the block of speech of 56bit includes
The data bit of 54bit and the control bit of 2bit；Control bit starts or terminates for identifying voice call.
Block of speech for regular length bit data, including data bit (speech bits) and control bit.Data bit is voice
Bit sequence after coding after Interleave Channel coding, carries useful acoustic information.Control bit leads to for carrying voice
Words such as start, terminate at the control information, and wherein voice starts, terminates that the two bit realizations in control bit can be adopted.When being embodied as
Control bit can also be increased newly by the length of extended voice block, to carry more control information.
When channel interleaving is carried out, processing module 102 can be used for the data bit of a block of speech by the dispersion that interweaves
To in S the first speech frame, S is the integer more than 2.
Wherein, S is also referred to as interleave depth, and interleave depth can be selected flexibly, and preferably 4 or 5.
Channel interleaving is encoded, for improving the signal fadeout of ultrashort wave wireless channel.Can be interweaved or convolution friendship using linear
Knit, channel interleaving coding is dispersed in S the first speech frame by the data bit of a block of speech, neighbouring between bit to change
Relation.S is bigger, and transmission characteristic is better, but propagation delay time is bigger.In practical application, flexibly selected depending on demand.During transmission
Prolong Td=tf× S, wherein tfFor the first speech frame duration.
First speech frame in addition to including the data bit after interweaving encoding, also including the control bit in original data block.
In embodiments of the present invention, processing module 102 first extracts data bit and control in decoding from the second speech frame
Position processed；Channel decoding is interleaved to data bit and obtains block of speech；Block of speech is decoded, the second raw tone is obtained.
Further, processing module 102 can be also used for super to opposite end in ultrashort wave transport module the first speech frame of transmission
Before short-wave radio set, lead code and synchronization character are sent to opposite end ultrashort wave radio set by ultrashort wave transport module.Lead code is used for
Receiving-transmitting sides bit synchronization, and firm power gain is to maximum, lead code sends immediately synchronization character after having sent, and synchronization character is used for
Recipient accurately judges the initial time of speech frame.The bit length of lead code and synchronization character is selected according to concrete radio channel state
Take, desirable 32 bits of lead code under generic condition, synchronization character can use 32 bits.
As shown in figure 3, speech frame 4 is obtained by multiple block of speech (3,4 ...) by intertexture；Sending each speech frame
Before need lead code and synchronization character, lead code and synchronization character before speech frame 4 be only shown, and not shown other languages in Fig. 3
The lead code and synchronization character of sound frame；Each block of speech includes data bit (being illustrated as 81bit) and control bit (being illustrated as 7bit).
Further, processing module 102 can be also used for after the synchronization character that opposite end ultrashort wave radio set sends is received, and surpass
Spending the very first time does not receive yet next synchronization character, determines end of conversation.
Wherein, the very first time can be 0.5S (second).
Specifically, when ultrashort wave radio set 100 does not carry out data is activation, give tacit consent to automatically into reception state, wait pending data.It is super
Short-wave radio set 100 is received after synchronization character, starts to receive the second speech frame.Ultrashort wave radio set 100 receives voice in control bit and leads to
End mark is talked about, or time-out does not receive the second new speech frame for 0.5 second, then it is assumed that this end of conversation.
Alternatively, processing module 102, are additionally operable to before to the first raw tone coding, and to the first raw tone language is carried out
Sound activity detection, to determine the first raw tone in voice beginning and end；When it is determined that voice starts in the first raw tone,
Start to encode the first raw tone；When it is determined that in the first raw tone at the end of voice, stopping to the first raw tone
Encoded.Doing so avoids the noise (without voice) to typing before and after user's speech to be encoded and sent, reduce
Transmission resource waste.
Further, bluetooth earphone 200 also includes：First link block 204, for setting up indigo plant with ultrashort wave radio set 100
Tooth wirelessly connects；Ultrashort wave radio set 100 also includes：Second link block 104, it is wireless for setting up bluetooth with bluetooth earphone 200
Connection.Wherein, bluetooth wirelessly connects and is set up by wireless blue tooth protocol, the nothing that bluetooth earphone 200 and ultrashort wave radio set 100 are supported
Line Bluetooth protocol includes HSP (Head set Profile) and HFP (Hand free Profile) etc..
Specifically, on ultrashort wave radio set 100 after electricity, the second link block 104 starts to find neighbouring bluetooth equipment, produces
Bluetooth equipment list.Second link block 104 selects bluetooth earphone according to the equipment class in Bluetooth protocol, and actively initiates bluetooth
Wireless pairing connects.If now bluetooth earphone is in pairing state, will finally set up between ultrashort wave radio set and bluetooth earphone
Wireless blue tooth connection.
After wireless connection is successfully established between bluetooth earphone and ultrashort wave radio set, bluetooth earphone passes through the acoustical signal of collection
Bluetooth wireless channel sends ultrashort wave radio set to, carries out speech processes.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
