Hamming Codes

We have previously discussed modulation and demodulation in wireless communications, now we turn our attention to channel coding. We know that in a wireless channel the transmitted information gets corrupted due to noise and fading and we get what are called bit errors. One way to overcome this problem is to transmit the same information multiple times. In coding terminology this is called a repetition code. But this is not recommended as it results in reduced data rate and reduced spectral efficiency.
