As a kind of embodiment, transmitting voice signal flow process (call or receive calls) is divided into up link and down link in the present invention, is described below for the processing procedure of up link, as shown below:
A/D changes
First, from the voice signal of transmitter (i.e. MIC) by an A/D converter and A/D conversion, be actually and become the code stream that every 125US contains 13bit through 8KHZ sampling, 13bits after quantizing, namely data flow is 104kbit/s;
Segmentation and speech coding
Data flow enters voice encryption device and carries out Regular-Pulse Excitation-long-term forecast (RPE-LTP) coding, PRE-LTP coding belongs to medium-rate mixed type coding, the speech analysis done for extracting characteristic parameter make use of the accurate stationarity of voice signal, namely can think within the short time of 10 ~ 20ms that the characteristic parameter of voice is constant.Therefore actual speech signal is divided into the short time period, the coded treatment of gsm system carries out according to frame, every frame 20ms, containing 160 speech samples, be the encoding block of 260bits after speech coding process, the signal rate namely after speech coding is 13kbit/s (i.e. 260bits/20ms=13kbit/s)
Chnnel coding
In order to detect and correct the mistake introduced between transmission period, introduce redundancy in a stream, its speed is improved by adding the information calculated from information source data. mention above, be 13Kbit/s by the code stream exported in speech coder, be divided into the continuous segment of 20ms, containing 260 bits in every section, 260bit is subdivided into again:
50 very important bits
132 significant bits
78 general bits
Different redundancy process is carried out respectively to them, Fig. 7 is the schematic diagram of channel coding process in the present invention, as shown in Figure 7, channel encoder first in speech signal most important 50 bits carry out block encoding (CRC check), produce 3 bit check positions, then form 185 bits with 132 significant bits, add 4 tail bits " 0 ", be combined as 189 bits, this 189 bit enters 1/2 rate convolutional encoder again, finally produces 378 bits.This 378 bit forms 456 final bit groups to the most insensitive 78 bits of wireless channel again with voice signal.Because every 20ms is one section, like this, we just obtain the data flow that speed is 456bits/20ms=22.8kbit/s.
Interweave
In encoded, voice composition is a series of orderly frames.And transmit time bit-errors normally paroxysmal, this will affect the correctness of successive frame.In order to correct random error and burst error, employing interleaving technology disperses these errors.
First this 456bit carries out interweaving in block of speech by interleave unit, and is divided into eight sub-blocks that length is 57bit.Interleaving technology limit due to length, can consult gsm protocol document, no longer describe in detail at this.
Ciphering unit
After the interblock carrying out adjacent block of speech interweaves, enter ciphering unit, encryption realizes by making exclusive-OR operation to 114 useful bits of a PRBS pseudo-random bit sequence and Normal bursts.Pseudo random sequence is obtained by burst signals and the prior session key set up by signaling method.The algorithm being used for producing pseudo random sequence is called " A5 " in gsm system specification.Data after encryption enter burst formatting unit.
Burst formatting unit
In this unit, 114bit data flow is added into the burst of training sequence and head, tail bit composition 156.25bit (comprising 8.25 protection bits), and these bursts are combined in different tdma frames and time slot by channel type goes.The reception of information, synchronous, balanced and information classification process are convenient in burst format.Data after format enter modulator.In the modulator GMSK modulation is carried out to the data after format.
Modulation
The modulation system of GSM is 0.3GMSK technology, and 0.3 illustrates the relation between the bandwidth sum bit rate of Gaussian filter.GMSK is a kind of special frequency-shift keying mode, and it, by increasing on a carrier frequency or reducing 67.708KHz, represents 0 or 1, is embodied as the I/Q signal after CPU modulation,
The I/Q signal that CPU modulates is through QN, Q, IN, I tetra-pins pass to transmitting and receiving module relevant pins, transmitting and receiving module then sends radio-frequency front-end to by TXOP_LO or TXOP_HI pin and amplifies, and is gone out by antenna transmission, Audio Processing Unit i.e. the above part that CPU is built-in, be illustrated for up link above, down link performs thinks anti-process.
Described video frequency program in the present invention also comprises the program on the Internet appreciated by mobile terminal, is not limited only to TV programme.
