Abstract
The main target of a 60 GHz transceiver system is to obtain data rates close to gigabit per second over short distances. The 60 GHz band suffers from severe path-loss, inter-symbol interference (ISI) and a limited link budget. To improve the link budget, we need to utilize beam-forming (BF) techniques. Antenna BF, i.e., combining signals from multiple receive antennas is one of the crucial aspects of the 60-GHz transceiver system.We consider uniform linear and circular antenna arrays for the proposed BF scheme. We use single carrier with frequency domain equalization (SC-FDE) modulation scheme in our system model. To suppress the ISI, we considered a cyclic prefix in the SC-FDE. The effects of physical parameters of antenna arrays on the bit error rate (BER) were investigated assuming both line of sight (LOS) and non-line of sight scenarios. We developed an efficient and computationally less complex beam-forming algorithm (BFA). We investigated the effects of perfect channel and non-perfect channel on the BER performance using the proposed BFA. We presented that the BER and sever ISI of 60 GHz band also improves using the proposed BFA.
