A new multilevel coding method that uses several error-correcting codes is proposed. The
transmission symbols are constructed by combining symbols of codewords of these codes. …

The distribution of the peak-to-average power ratio (PAPR) in strictly band-limited orthogonal
frequency-division multiplexing (OFDM) signals is studied. Assuming that the base-band …

We analyze the performance of the clipped orthogonal frequency division multiplexing (OFDM)
system in terms of peak power reduction capability and degradation of channel capacity. …

A basic theory of two-dimensional cyclic codes (TDC codes) is presented. This theory is
applicable to the binary TDC codes of odd area, ie, the TDC codes with an odd number of …

This paper discusses an asymmetric cryptosystem C* which consists of public transformations
of complexity O(m 2 n 3 ) and secret transformations of complexity O((mn) 2 (m + logn)), …

Two simplified versions of the belief propagation algorithm for fast iterative decoding of low-density
parity check codes on the additive white Gaussian noise channel are proposed. Both …

An overview of the many practical applications of channel coding theory in the past 50 years
is presented. The following application areas are included: deep space communication, …

Without loss of generality, we assume hereafter ABCs to be used for providing secrecy: the
encipherment (resp. decipherment) is operated with the public (resp. secret) keys. This …

The performance of the strictly band-limited OFDM systems with deliberate clipping is
examined in terms of the peak-to-average power ratio (PAPR) and the resultant bit error …

Attribute-based encryption (ABE) system enables an access control mechanism over encrypted
data by specifying access policies among private keys and ciphertexts. There are two …
