SphereDecoding

Implementation of Sphere Decoding on Verilog

How to run

Use the MATLAB file H_generator.m (first section) to generate the input data, testbench.mem.
In H_generator.m, set the SNR as you want.
testbench.mem will have 500 channel matrices, and 11 inputs for each channel matrix.
To simulate the whole things, run top_tb.v.
To compare the performance, use Data_Out.txt from the top_tb.v and run the H_generator.m (second section).

Ordering the nodes so that the nearest node of that particular input is visited first.
Pre-setting the radius so that the searching time is less.
Changing the fixed-point precision and input width to be lesser (?)
