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: |
