常见的插值函数是interp1,可以在MATLAB中help interp1中学习一下。下面给出的MATLAB代码也是使用的interp1这个插值函数。 除了上面基于导频的估计方法,其实ODFM还有基于判决反馈的信道估计方法、基于DFT的信道估计、基于叠加信号的信道估计、盲信道估计等等方法,在《MIMO-OFDM无线通信技术及MATLAB实现》中均有介绍。 基于D...

OFDM Demodulation with Different CP Lengths Copy Code Copy Command OFDM-demodulate a signal with different CP lengths for different symbols. Initialize input parameters defining locations for null and pilot subcarriers. Generate random data and perform OFDM modulation. Get M = 16; nfft = 64; cp...
PROBLEM TO BE SOLVED: To produce the continuous sample clock signals at high speed and with high accuracy without effects from adjacent carriers on the receiving side by assigning both end carriers among many subcarriers of an OFDM modulating spectrum as the sample clock reproduction reference ...
To meet this requirement, Harman Becker engineers created a customized DQPSK block in MATLAB, which they included in their Simulink model as a MATLAB S-function. The team captured real-world digitized intermediate frequency (IF) data produced by an RF front end. To verify the OFDM demodul...

The block provides an interface and architecture suitable for HDL code generation and hardware deployment. The block accepts input data either at maximum rate of 30.72 MHz, or at a sample rate corresponding to NDLRB. The input sampling rates for NDLRB 6, 15, 25, 50, 75, and 100 are 1.92...
You can use a vector input to increase the data throughput and achieve a giga-sample-per-second (GSPS) throughput. The block provides an interface and architecture suitable for HDL code generation and hardware deployment. Examples OFDM Demodulation of Streaming Samples Demodulate complex time-domain ...
