Beam-pattern-scanning dynamic-time block coding: Achieving high performance

In this paper, we introduce a novel transmit diversity in which the space diversity in space-time block codes (STBC) is combined with time diversity created by Beam Pattern Scanning (BPS). Via this merger, we achieve high bit-error-rate (BER) performance via time diversity inherent in BPS and space-time codes in STBC. A dynamic time (that is, time-varying) block coding (DTBC) is introduced to compensate the effect of time varying array vectors applied to the array elements in BPS. Hence, we call the scheme BPS dynamic time block coding (BPS/DTBC). We discuss the structure of the BS antenna array and receiver, and generate the BER performance simulations. © 2006 IEEE
