Description/Abstract
A combined scheme based on Orthogonal Frequency-Division Multiplexing and Frequency-Hopped Multiple Access (OFDM/FHMA) is proposed, in which the transmitted data is spread over both the time and frequency axes without expanding the bandwidth. The OFDM system advocated employs the Walsh-Hadamard Transform (WHT) for spreading the data in the frequency domain and weights the received signal by the estimated Signal-to-Interference Ratio (SIR) for the sake of reducing the effects of interference. The performance recorded, when communicating over an interference-limited channel suggests that the achievable BER improvement is as much as an order of magnitude in comparison to that of an OFDM/FHMA scheme dispensing with WHT.
