Direct-conversion transceiver obtains increasing attentions due to its low power consumption, but it confronts with serious IQ imbalance. In this paper, a three-stage treatment of transmitter/receiver (TX/RX) IQ imbalance and channel, in the presence of carrier frequency offset (CFO), is proposed for single-carrier-frequency-domain-equalization (SC-FDE) systems. First, RX IQ imbalance and CFO are...
Due to the extremely high oscillation frequency of 60 GHz systems, phase noise (PN) imported at both transmitter (Tx) and receiver (Rx) is significant, which degrades the transmission performance. This paper proposes an architecture employing iterative Tx and Rx PN compensation (ITR-PNC) for 60 GHz systems with single-carrier frequency-domain equalization (SC-FDE) transmission. The ITR-PNC iteratively...
The direct-conversion transceiver is an attractive architecture for 60 GHz wireless systems to meet the low-cost and low-power-consumption requirements, but it suffers from the IQ imbalance problem seriously. This paper adopts second-order moment estimation to extract frequency-independent IQ imbalance parameters, and performs IQ compensation based on the estimation results. In order to achieve robust...
In this paper, we make a performance comparison between convolutional(171,133) codes (CC), concatenated RS(255,239)-convolutional(171,133) codes (RS-CC) and LDPC(672,336) based on 60GHz single carrier physical layer (SC-PHY). With the effect of phase noise and non-linear distortion of power amplifier (NLPA) taken into account, RS-CC reveals higher robustness against the effect over LDPC, and it has...
In this paper, we propose a modified preamble based channel estimation for the orthogonal frequency division multiplex/offset QAM (OFDM/OQAM). In present of multi-path effect, the inter symbol interference (ISI) always exists in the OFDM/OQAM system and the preamble based channel estimation for the conventional orthogonal frequency division multiplex with cyclic prefix (CP-OFDM) is not feasible any...
