Encryption White Paper
To scramble plaintext original data into ciphertext the encrypted version you need an algorithm and a key. The algorithm defines which encryption method is used, while the key cites a specific instance of the algorithm. The following example explains this further.

Bayesian Blind Parafac Receivers for DS-CDMA Systems
This paper proposes a new Bayesian blind detection/identification algorithm for CDMA system in presence of spatial diversity at the receiver. Such algorithm provides good performance even for short frame length (typically, 10 symbol periods) and for large system load. Furthermore, simulation results show that the proposed method is close to...

The Papoulis-Gerchberg Algorithm With Unknown Signal Bandwidth
The Papoulis-Gerchberg algorithm has been extensively used to solve the missing data problem in band-limited signals. The interpolation of low-pass signals with this algorithm can be done if the signal bandwidth is known. In practice, the signal bandwidth is unknown and has to be estimated by the user, preventing an...
