In order to improve the performance of non-binary low-density parity check codes (LDPC) hard decision decoding algorithm and to reduce the complexity of decoding, a sum of the magnitude for hard decision decoding algorithm based on loop update detection is proposed. This will also ensure the reliability, stability and high transmission rate of 5G mobile communication. The algorithm is based on ...

This paper presents a design technique for high fidelity multistage decimation filters based on the polyphase and decimator structures presented in [1][2], catering for powers of two sample-rate decreases. The technique is well suited for Analog-to-Digital Converter (ADC) applications in excess of 16 bit resolution. The resulting filter coefficients are constrained to the required bit length us...

The paper addresses tlie design of tlie polyphase IIR filters based on the “’-order single-coefficient allpass sub-filters in the constraint coefficient space using the Constraint Dowdiill Simplex Algorithm. Incorporating the bit-flipping algorithm into its core engine allowed the optitilisation routine to converge to better target designs without affecting tlie Iiigli speed of tlie original al...

Based on α-stable random projections with small α, we develop a simple algorithm for compressed sensing (sparse signal recovery) by utilizing only the signs (i.e., 1-bit) of the measurements. Using only 1-bit information of the measurements results in substantial cost reduction in collection, storage, communication, and decoding for compressed sensing. The proposed algorithm is efficient in tha...

Lo and Chau [7] showed that ideal quantum coin flipping protocol is impossible. The proof was simply derived from the impossibility proof of quantum bit commitment [7, 8]. However, the proof still leaves the possibility of quantum coin flipping protocol with arbitrary small bias. In this paper, we show that quantum coin flipping protocol with arbitrary small bias is impossible and show the lowe...

Nowadays Low Density Parity Check Codes (LDPC) is more in demand in Wireless Communication Systems due to its excellent performance. Use of LDPC code for encoding and decoding purposes found to be more reliable and highly efficient data transfer over wide bandwidth in presence of corrupting noise. Various Algorithms were used to interpret LDPC codes. Out of which Sum Product Algorithm and Min S...

Quantum protocols for coin flipping can be composed in series in such a way that a cheating party gains no extra advantage from using entanglement between different rounds. This composition principle applies to coin-flipping protocols with cheat sensitivity as well, and is used to derive two results: There are no quantum strong coin-flipping protocols with cheat sensitivity that is linear in th...
