In the present embodiment, the part interleaver also can be described with formula, and for example, interleaver a can be used for p
i=[(19n+1) mod 48] are represented, n=0, and 1 ..., 47.
In the present embodiment, k coded-bit modulated according to preset modulation system before transmitting terminal can be chosen from 48 coded-bits after the rearrangement, and modulation symbol is mapped on the physical channel according to the form of presetting sent; Wherein, k is greater than 0 and less than 48.Be that transmitting terminal can carry out truncation to 48 coded-bits after the rearrangement, obtain to satisfy the modulation symbol of number needs.
Present embodiment utilizes the encoder matrix shown in the table 2 that information bit coding to be sent is generated 48 coded-bit b
i, utilize interleaver a to interweave then and obtain 48 coded-bit b to any interleaver among the interleaver k
i', then adopt the QPSK modulation to obtain 24 QPSK symbols, send 24 QPSK symbols according to the DFT-S-OFDM in the LTE-APUCCH form (DFT-Spreading-OFDM) form.
For the ease of the information bit felt properties in the information bit sending method of observing present embodiment, be representative with interleaver j, h below, provide of the comparison of the information bit felt properties of present embodiment with respect to prior art two performances.Wherein, Performance is relatively through The Realization of Simulation, and simulated conditions is: 5MHz bandwidth, classical city (TU:Typical Urban) channel; The user equipment (UE) translational speed is 3 kilometers/hour; Antenna frame is 12 to be received, and adopts actual channel to estimate that transformat is the DFT-S-OFDM form of LTE-A PUCCH form.
Please consult Fig. 7 and Fig. 8 in the lump, Fig. 7 and Fig. 8 are respectively that the number to information bit to be sent is the simulation result sketch map of 6bit and 7bit.Wherein, abscissa is represented signal to noise ratio (snr) among Fig. 7 and Fig. 8, and unit is dB; Ordinate represent Block Error Rate (Block Error Rate, BLER); It is good more to reach the more little expression performance of SNR that identical BER needs this moment; Can find out from simulation result, reach identical BLER=10
-2The time, interleaver 1～5 needed SNR is all little than prior art two, so the performance of the embodiment of the invention is superior to the performance than prior art two.
In the information bit sending method that present embodiment provides; K bit carried out the QPSK modulation before transmitting terminal can be chosen from 48 coded-bits after the rearrangement; Obtain the QPSK symbol and be mapped to PUCCH to send; 48 coded-bits after promptly can the counterweight new sort carry out truncation, obtain to satisfy the QPSK symbol of number needs.
In the embodiment of the invention, at first information bit to be sent is encoded, generate 48 coded-bit [b based on encoder matrix
0, b

0, b
1, b
2..., b
47In do not carry the neighbor information bit discrete distribution of the information of some or a plurality of information bits to be sent; 48 coded-bits after will arranging again at last carry out the QPSK modulation, obtain a series of QPSK symbols and be mapped on the ascending physical signal control channel to send.The embodiment of the invention is at 48 coded-bit [b that carry out will generating before the QPSK modulation
0, b
