The information on the code to be simulated must be input in the definition
file "def.h" in addition to using the corresponding generator matrix

Example: 

A BCH(32,6,16) is to be simulated. 

(1) The "def.h" file should contain the following three lines:

#define N 32
#define K 6
#define D_H 16


(2) Assume that order-5 decoding is to be simulated. Then compile (linux) as:

gcc -O2 osd_order5.c order5.c -lm


(3) Execution of the simulation program:

a.out genmat.32.06.16 ber.data -5 -2 1 100000 12344567

Simulation of soft-decision decoding with ordered statistics
This is a (32,6,16) linear code with generator matrix:
(IMPORTANT NOTE: The matrix MUST be in systematic form)
