Description: Hamming codes can detect up to two-bit errors or correct one-bit errors without detection of uncorrected errors. By contrast, the simple parity code cannot correct errors, and can detect only an odd number of bits in error. Hamming codes are perfect codes, that is, they achieve the highest possible rate for codes with their block length and minimum distance Platform: |

Description: A noncoherent, bandwidth-efficient modulation
scheme is proposed for frequency-hopping multiple-access
(FH-MA) networks. The proposed scheme is a combination
of noncoherent -ary amplitude-shift keying (NMASK) and
orthogonal frequency-division multiplexing (OFDM). Using
this scheme will minimize the required data bandwidth. The
number of frequency slots available to the users will increase
significantly for a fixed spread-spectrum bandwidth (BW55).
The effect of the multiple-access interference will be reduced.
Simple and accurate bit error rate expressions have been derived
for FH-OFDM-MASK in additive white Gaussian noise channels
and for FH-OFDM-ASK in Rayleigh fading channels.
Index Terms—Amplitude-shift keying (ASK), frequency hopping
(FH), -ary amplitude-shift keying (MASK), noncoherent,
orthogonal frequency-division multiplexing (OFDM), Rayleigh
channels. Platform: |

Description: In this paper, the problem of estimation
of fast time-varying radio channels is considered. A
new algorithm, Iterative Channel Estimation is
presented. This algorithm is designed for radio
channel estimation in multiple-input multipleoutput
systems with space-time block coding. The
channel transfer matrix is estimated on the basis of
a previously decoded data, so it can be performed
simultaneously with the data transmission. The
estimation process is a simple operation, just a
multiplication of two matrices. As a result, bit error
rate is reduced. The algorithm is compared to the
differential space-time block codes and verified by
Monte-Carlo simulations. Platform: |
