An apparatus and method for determining an optimum modulation scheme and code rate in a communication system using a variable transmission scheme. In a transmitter included in the communication system, an encoder encodes an encoder packet (EP) and a plurality of modulators having different modulation...
动量的另一种计算方式是做除法,即 t 期的价格减去其 m 期以前的价格 P_{t-m},再除以P_{t-m}。做除法求出的动量值衡量的是价格变化的比率,用公式表示 t 时期的 ROC(Rate of Change)为: 1. AI检测代码解析 其中,ROC_t 表示股票 t 时期的 m 期动量值(价格变化率),P_t 表示股票 t 时期的价格,m...
Code Rate Code ratecan be defined as theratiobetween useful bit and total transmitted bit (Useful + Redundant Bits). These Redundant bits are added for Forward Error Correction(FEC). In other words we can it is the ratio between the number of information bits at the top of the Physical la...
It is a two-dimensional representation that has the time dimension on the abscissa and the lag time (repetition rate or tempo) on the ordinate. The beat spectrogram visualizes how the tempo changes over time and allows for a detailed analysis of the rhythmic structures and variations. Note ...
env = inph + 1j*quad; g = timetable(env,SampleRate=fs); Open Signal Analyzer and drag the complex envelope from the Workspace Browser to the Signal table. The display shows the in-phase and quadrature components of the envelope as lines of the same hue and saturation, but different lumin...
This MATLAB function modulates the real message signal x with a carrier frequency fc and sample rate fs.
The choice of the frequency deviation Δf depends on the available bandwidth, the bit rate BT and the demodulation scheme used in the receiver. The modulation index m is given by [7]m=2ΔfBT The minimum value of m that produces orthogonality (for independent detection of the 0s and 1s)...
Transmit and receive data using a nonrectangular 16-ary constellation in the presence of Gaussian noise. Show the scatter plot of the noisy constellation and estimate the symbol error rate (SER) for two different SNRs. Create a 16-QAM constellation based on the V.29 standard for telephone-line...
2G). Although informativeness is correlated with the mean firing rate of a unit (Supplementary Note S5), a partial correlation analysis confirmed that firing rate differences cannot explain the inferred modulation targeting, as firing-rate-corrected informativeness and modulator couplings are significantly...
