  This work presents an experimental study of Single Input Multiple Output
(SIMO) channel performance in indoor radio propagation environment. Indoor
channel measurements at 2.4 GHz ISM frequency band have been performed using a
versatile channel sounder testbed platform. A single transmitting antenna, four
receiving antennas with two proposed geometries and a four-branch receiver
circuitry were used in order to achieve channel sounder measurements exploiting
baseband signal processing techniques. Deep investigation on SIMO wireless
channel performance was realized through three types of metrics which are
signal strength, gain coefficient and capacity. Performance results indicate
SIMO channel capacity enhancement and illustrate differences between the two
proposed geometries.
