چکیده
In this paper, a Low-Density Parity-Check (LDPC) coded Orthogonal Frequency-Division Multiplexing (OFDM) wireless communication system based on IEEE 802.11a standard is studied and a simplified LDPC decoding initialization algorithm is proposed. Simulation results showed that this algorithm is effective and can fasten decoding procedure. Appling this algorithm the LDPC decoding performance is satisfied when the maximum iteration number is 10. Key-words:IEEE 802.11a standard; LDPC codes; OFDM system; decoding initialization algorithm

Multicarrier systems may be implemented using different filter bank multicarrier (FBMC) modulation schemes. In this paper, we compare three FBMC techniques, i.e., OFDM, OFDM-OQAM and WPM, based on multiple criteria, including bandwidth efficiency, computational complexity, latency, out-ofband emission, peak-to-average power ratio, and sensitivity to timing and frequency offsets. An efficient im...

If the degree distribution is chosen carefully, the irregular LDPC codes can outperform the regular ones. In this paper, we proposed an LDPC coded BICM scheme in image transmission system to improve both efficiency and reliability. Simulation results show that LDPC codes are good coding schemes over fading channel in image communication with lower system complexity. Simultaneously, irregular co...

This paper presents two algorithms; the first one is used to convert between Product of Sums (POS) and Positive Polarity Dual Reed-Muller (PPDRM) forms. The second algorithm is used to compute all the coefficients of the Fixed Polarity Dual Reed-Muller (FPDRM) with polarity p from any polarity q. This technique is used to find the best polarity of FPDRM among the 2 fixed polarities. The algorit...

Abstract—A low-complexity, high-accurate frequency offset estimation for multi-band orthogonal frequency division multiplexing (MB-OFDM) based ultra-wide band systems is presented regarding different carrier frequency offsets, different channel frequency responses, different preamble patterns in different bands. Utilizing a half-cycle Constant Amplitude Zero Auto Correlation (CAZAC) sequence as...

This paper investigates the effects of phase noise on the performance of Polynomial Cancellation Coded Orthogonal Frequency Division Multiplexing (PCCOFDM). Phase noise will cause two effects on PCCOFDM, one is a Common Phase Error (CPE) and the other is Interchannel Interference (ICI). CPE is constant for all subcarriers in a symbol so that it can be corrected using existing techniques while t...
