perfoms a forward fast hankel transform

LTE system, OFDM modulation and Turbo Coding, including Viterbi, BCJR and SOVA are extensively analysed, ending up with a system performance specification. These are used to implement a fixed length Turbo encoder, a 16-QAM modulator and a 16 point IFFT on an FPGA using MATLAB Simulink⃝ R with Xilinx⃝ R System Generator plugin. A MATLAB⃝ R script is developed to test the Simulink implementation. In addition, an iterative Turbo decoder is programmed using MATLAB⃝ R .
