Familiarity with HW/DSP implementations of some of the following technologies desired: FFT, Turbo decoder, LDPC decoder, Digital Front End, Equalizer, Channel Estimate. The number of LDPC decoder iterations is de-termined by NI, ranging from 0 to 63. 04237*x^2+0. The MATLAB class mpdecoder actually calls the C++ class MPDecoder through the MATLAB MEX interface, which ensures its high decoding speed. Reed-Solomon encoding and decoding can be carried out in software or in special-purpose hardware. With the use of a large number of cores in the GPU to perform the simple computations simultaneously, our GPU-based LDPC decoder can obtain hundreds of times speedup compared with a serial CPU-based simulator and over 40 times speedup compared with an 8-thread CPU-based simulator.
