Include K1Bit number, Ns=Nb/K1。
Step S1064 carries out offset overlapping multiplexing coding to the second coded data, obtains first coding data.
Specifically, above-mentioned offset overlapping multiplexing coding is (Shift-OvXDM, referred to as S-OvXDM), namely is generally made
OvXDM coding, effect is that multivariate data stream is carried out displacement overlapping.Its shift intervals is K1*Tb, being overlapped tuple isExpression rounds up.The duration for being multiplexed waveform is Tλ=λ * K1*K2*Tb.Wherein λ is wave
Shape ceofficient of spread, is defined as: width T1Rectangular wave by filtering after broadening be T2, pulse width coefficient lambda=T2/T1.Square
λ=1 of shape wave, T2Refer to the waveform widths for accounting for gross energy 99.99% or 99.999%, is selected by the height of required η, it is clear that λ >=
1。

Due to being divided into K between " impact " of input1*TbIf S-OvTDM multiplexing waveform h (t) is that width is T=K1*K2*TbRectangular wave, then
The overlapping tuple of S-OvTDM is K2；If the h (t) of S-OvTDM is that width is Tλ=λ * K1*K2*TbNon-rectangle wave, then its be overlapped
Tuple will be increased toExpression rounds up.Such as K1=2, Tb=1, K2=3, if λ=1, S-
The width T of corresponding multiplexing waveform h (t) of OvTDMλ=6, overlapping multiplexing numberIf λ=1.2, S-OvTDM couple
The width T of the multiplexing waveform h (t) answeredλ=7.2, overlapping multiplexing number
Assuming that the second coded data is P=PI+j*PQ, which is Ns, S- is transmitted to using the sequence as input
The input terminal of OvTDM coding is multiplied respectively to each data with multiplexing waveform h (t), ask it is cumulative and, calculating process is equal
In general OvTDM process.The output symbol stream y (namely above-mentioned first coding data) for being distributed in I, Q two-way is obtained, will be believed
Number launch.Expression formula are as follows: y=∑ Pi*h(t-i*ΔT)。
By taking S-OvFDM as an example, the equivalent waveform convolutional encoding model phase of equivalent waveform convolutional encoding model and S-OvTDM
Seemingly, difference is only that multiplexing waveform is H (f), obtains the frequency-region signal for being distributed in I, Q two-way, and frequency-region signal is anti-by fourier
Transformation is converted to time-domain signal and launches using antenna.Expression formula are as follows:
