A novel space-time FFH-MIMO system with generalized wide-interval fh patterns

This paper presents a novel space-time fast frequency hopping (FFH) multiple input multiple output (MIMO) wireless communication system over rayleigh fading channel. With the M-ary frequency shifting keying (MFSK) modulation and noncoherent demodulation, the structure of a new system is discussed based on the combination of FFH technique and MIMO system. The concept of generalized wide-interval FH (WFH) pattern is put forward. Corresponding design method of WFH pattern is given and applied to the new system. Because of the high diversity order offered by both FFH technique and multiple receive antennas, this novel system may achieve much higher transmitting rate and favorable bit error ratio (BER) performance at the same time compared with conventional FFH single input single output (SISO) system.
