In land mobile communication, CMA (Constant Modulus Algorithm) has bee
n studied to reduce multipath fading effect. By this method, the trans
mitted power is not used efficiently since all the multipath component
s have the same information. To make use of received power efficiently
, we propose a Blind Multiple Beam Adaptive Array. It has the followin
g three Feature points. First, we use CMA which can reduce the multipa
th fading effect to some extent without training signal. Second, LMS a
lgorithm which can capture the multipath components which are separate
d from the reference signal by some extent. Third, we use FDF (Fractio
nal Delay Filter) and TED (Timing Error Detector) loop which can detec
t and compensate fractional delay. As a result of utilizing the multip
ath components which is suppressed by CMA, the proposed technique achi
eves better performance than CMA adaptive array.
