Abstract
In this contribution we focus on the physical layer of UMTS Long Term Evolution (LTE) and propose an alternative transceiver concept which might be considered for further extensions of the standard. A simple repetition code is combined with a complex mapper with bit doping resulting in a Bit-Interleaved Coded Modulation with Iterative Decoding (BICM-ID) scheme. Allowing feed-back based multiple transmissions of the same coded frame similar to the hybrid automatic repeat-request scheme employed in UMTS LTE, we show that the performance in terms of goodput (error-free throughput) of the proposed BICM-ID scheme is comparable to UMTS LTE for high order modulation schemes (16QAM, 64QAM) for the considered cases, while the receiver complexity is significantly reduced.
