In a cellular network, randomness is introduced into a transmitted signal at each transmitter, and the resulting received signal, which is the sum of all received signals, fluctuates more in time than a signal transmitted without the introduced randomness. While the introduction of randomness can diminish reception of some parts of the signal at the receiver, the transmitted signal can be encoded using forward error correction coding techniques, which allows the receiver to recover all of the signal information despite some diminished reception. Such randomization provides time diversity so that receivers can have more consistent performance. For broadcasted data, where users with the worst channel condition dictates the overall performance, having consistent performance across users can improve the overall network performance.
