Abstract--In this paper, diversity analysis of bit-interleaved
coded multiple beamforming (BICMB) is extended to the case
of general spatial interleavers, removing a condition on their
previously known design criteria and quantifying the resulting
diversity order. The diversity order is determined by a parameter
Qmax which is inherited from the convolutional code and the
spatial de-multiplexer used in BICMB. We introduce a method to
find this parameter by employing a transfer function approach as
in finding the weight spectrum of a convolutional code. By using
this method, several Qmax values are shown and verified to be
identical with the results from a computer search. The diversity
analysis and the method to find the parameter are supported by
simulation results. By using the Singleton bound, we also show
