摘要： A plurality of three bit units (called triplets) are permuted by a shuffler to shuffle the positions of the triplets into different patterns which are used to specific the read/write operation of a memory. For example, the least significant triplet in a conventional counter can be placed in the most significant position of a permuted three triplet pattern. The count of this permuted counter triplet generates addresses that jump 64 positions each clock cycle. These permutations can then be used to generate read and write control information to read from/write to memory banks conducive for efficient Radix-8 Butterfly operation. In addition, one or more triplets can also determine if a barrel shifter or right circular shift is required to shift data from one data lane to a second data lane. The triplets allow efficient FFT operation in a pipelined structure.

摘要： The 60 GHz channel between the transmitter and receiver can have AWGN characteristics allowing a Time Domain Equalizer (TDE) to be used at the receiver instead of a Frequency Domain Equalizer (FDE). The complexity of performing matrix inversion on a received signal is reduced when directional antennas are used in a 60 GHz system. Incorporating the TDE in place of the FDE saves almost an order of magnitude in power dissipation. For portable units, such a savings is beneficial since the battery life can be extended. The signal quality of wireless channel is based on the characteristics of the received signal to switch the equalization operation from a system performing FDE to TDE and vice versa. The receiver adapts to the received signal to reduce the power dissipation of the system.

摘要： In an up-converter path of a transmitter, wide-band signal system like direct conversion WiGig, a high pass filter (HPF) is placed in the baseband path after the low pass filter (LPF) but before the mixers. The baseband signal of WiGig can have a bandwidth of 800 MHz. The HPF removes the frequencies from 0-40 MHz from the baseband signal and degrades the overall signal of the baseband by a dB or so. However, the frequency pulling is significantly reduced since oscillator frequency and Radio frequency (RF) transmitter frequencies after conversion become further separated when compared a system using to the conventional approach. This causes the injected signal to fall outside the locking range of the oscillator. The concern of substrate coupling is reduced and allows for a reduction in the physical distance between the oscillator and the mixer and reduces a shift in the desired target frequency of operation.

摘要： A portable unit with an endfire antenna and operating at 60 GHz makes an optimum communication channel with an endfire antenna in an array of antennas distributed over the area of a ceiling. The portable unit is pointed towards the ceiling and the system controlling the ceiling units selects and adjusts the positioning of an endfire antenna mounted on a 3-D adjustable rotatable unit. Several transceivers can be mounted together, offset from one another, to provide a wide coverage in both azimuth direction and elevation direction. These units can be rigidly mounted as an array in a ceiling apparatus. The system controlling the ceiling array selects one of the transceivers in one of the units to make the optimum communication channel to the portable unit. The system includes the integration of power management features by switching between Wi-Fi in favor of the 60 GHz channel.

摘要： Transceiver calibration is a critical issue for proper transceiver operation. The transceiver comprises at least one RF transmit chain and one RF receive chain. A closed loop path is formed from the digital block, the RF transmit chain, the substrate coupling, the RF receive chain back to the digital block and is used to estimate and calibrate the transceiver parameters over the operating range of frequencies. The substrate coupling eliminates the need for the additional circuitry saving area, power, and performance. In place of the additional circuitry, the digital block which performs baseband operations can be reconfigured into a software or/and hardware mode to calibrate the transceiver. The digital block comprises a processor and memory and is coupled to the front end of the RF transmit chain and the tail end of the RF receive chain.
